2026 GJMAT Gold Award





Recently, I took GJMAT, an India-based mathematical competition. It was an online competition and overall pretty interesting.

In total, there were 25 problems to solve. The first 10 were only worth 2 points each, problems 11~20 were worth 4 points each, and the last 5 problems were worth 8 points each.

When the exam started, I started from the first problem. However, I got stuck when I hit the third problem. So I decided to jump to the last problem and work my way backwards to earn the most points.

Surprisingly, I was able to complete most problems. I still missed a few problems, but I had confidence on around 20 of the problems. 

Not only was the math itself hard, but understanding the Indian English was also a challenge. Sometimes I couldn't fully understand the problem quickly. 

Recently, the results came out, and I was lucky enough to receive the gold award. Unfortunately, they didn't provide my scores and ranking.

Overall, the GJMAT was a fun experience. I had fun working on the problems, and ultimately I won the gold award. Sadly, I think GJMAT is only available up to grade 10. So this was one of the last years I could join GJMAT.

My VEX World Championship 2026 Experience





This blog documents my trip to the VEX World Championship in St. Louis. I was able to experience a lot, meet the true top teams in the world, and learn from them.

This was my first year competing in the VEX V5 Robotics Competition, and along with my great teammates, we were able to qualify for the World Championship in the PAS-VEX Signature Event in December.

The VEX World Championship was featured over 800 teams from around the world, representing a scale entirely different from any other competition we have attended.


Pre-Competition Practice





Before the competition, we held practice matches in a conference room we rented and invited teams to join and practice together. We were honored to have both 334C and 334U join the games. They were the best teams in the world, on a completely different level compared to all teams in Taiwan.

Both 334C and 334U had two wings, and they were really good at using them. So we couldn't win in a wing battle against them at a long goal. That's why we switched strategy and avoided directly fighting them. We would score mainly in the center goals, and only dump on the long goals at the end. As a result, we were able to win a match against them by a slim margin. 

Being able to practice with these top teams really changed me. I realized that they were so much better than us. In the next season, we shouldn't aim only for the champions in Taiwan, but also aim to become a world top team.


Competition + Getting Sick



Unfortunately, I became really sick on the first day of the competition. Therefore, I only competed in the afternoon. We won the practice match but lost our first qualification match.

I returned early on the first day and rested in the morning of day 2 until I was called to the convention center because we had a team interview. So despite being pretty sick and having almost no voice, I raced to the convention center and completed the team interview along with my teammates.

For day 2, we won 3 matches and lost 2 in total. Our ranking was around the 30s, which was pretty bad. At night, we fixed the robot to make our intake less likely to overheat. 

We had a really easy match schedule on day 3, and along with our fixed robot, we were able to win all 5 matches. We ended up 15th on the qualification ranking. This guaranteed us a seat in the elimination, but we still had to talk to top ranking teams to seek alliance.


Eliminations




Finally, after 8 alliances, 18961B picked us and we accepted. Forming the 9th seed. 18961B was a team from China and they had a pretty nice robot. So we practiced auto together and headed to the elimination rounds.

The first match was the round of 16; we faced 13722V and 3632A. We fought a pretty tough match, but we ultimately won with a 15-point margin.




The quarterfinal round was really challenging because our opponents were the first seed in our division, 11101X and 10222R. Luckily, we were able to take 2 goals and our alliance partner got a park. We ended up winning the quarterfinal by 12 points.

The semifinal round was even harder, with 81988E and 15442A as our opponents. 81988E had the ability to block both center goals, making it hard for us to win the center. During the match, they blocked the center goal. Unfortunately, our teammate got stuck with them in the center goal, and we lost the match by a good margin.


Conclusions





Although we were stopped in the semifinal, we were able to get the Create Award in our division. We were really glad that we didn't have to go home empty-handed. 

Overall, I really enjoyed this year's VEX World Championship. Practicing with 334C and 334U really made me realize how good other teams were. We also did quite well in the tournament as we won 9 out of 12 qualification matches. Forming the 9th seed, we defeated the 8th seed and 1st seed and went into the semifinal round. Finally, the Create Award recognizes our work on the notebook, interview, and robot.

I had a great experience. Unfortunately, I was really sick for most of the competition. I'm sure I would've had a lot more fun if I was 100% healthy. 

Finally, I have to thank my teammates who made the team so well-rounded. Thanks to our sister teams for constantly practicing with us. Thanks to our coach who taught us a lot throughout the season. Thanks to all of the teams we met during the competition for making VEX Worlds fun. Thanks to the parents who were willing to support us no matter what.

2026 AIME II 8/15





This is my first year competing in AIME. I thought it would be really hard, but I ended up with 8 questions answered correctly, way above my expectations before taking the test.

After getting an 118.5 on the AMC 10A last year, I qualified for this year's AIME. To prepare for the AIME, I tried looking at some of the problems from 2025 and 2024. It turned out that I could barely solve any of the problem. That's why I thought I was cooked for this year's AIME.

For the next few weeks, I decided to start taking one test every week, starting from 1983, so I could build up confidence and actually get some questions correct.

On the day of the test, my expectation was that I could get 3 to 4 questions right. But when I really started working on the problems, they turned out being really easy, at least a lot easier than the previous problems.

The first 5 problems were quite easy and I completed them quickly. Then I continued finishing questions 6 to 8. After question 8, the problems became so difficult that I couldn't even think of a way to approach them. Just when I was desperate, I saw question 15, and it was surprisingly easy to solve. 




The whole test was 3 hours long, and I only had 15 problems to work with. So after finishing all problems that I could solve, I started drawing and writing random things, including names of small Japanese political parties. For the last 30 minutes, I pretty much slept until the bell rang.




Fast forward to a few weeks ago, the scores came out. I got 8 correct out of the 15 problems. It turned out that I missed question 6 unfortunately. Finally, out of the 270 contestants in Taiwan, I was in the top 41. There was one person who scored a 15, which is totally unbelievable.

Overall, it was a really fun experience to compete in the AIME. I hope I could still qualify for the AIME and do even better next year.

自學第八年 回顧與自評 / Yu

回顧期間:2025 / 4 - 2026 / 3   填寫日期:2026 / 3 / 20

1. 這是自學的第八年,對鎮宇來說,已經要開始考慮申請大學了。想先請鎮宇介紹一下,過去一年,你在學科方面的努力,包括:台灣國民教育教材學習了哪些,以及開始讀的 AP 課程等。




過去一年,我把國民教育的課程裡面想學的都學完了,包括以下科目:

高中數學二上、二下
高中選修物理 I
高中地理二上
高中歷史二上
高中公民二上

另外,我也開始準備 AP 的各科,今年我打算考六個科目,包括:

AP Calculus AB
AP Statistics
AP Physics 1
AP Human Geography
AP World History: Modern
AP Japanese Language & Culture

我覺得國民教育的內容先學完很好,讓我學習 AP 科目變得輕鬆很多,而 AP 各科我現在讀完內容,開始大量考模擬考了,目前我在模擬考都可以拿到 5 分。


2. 今年你也投入了 VEX V5 的比賽,從 IQ 轉 V5,心得很多。請跟我們分享一下,這個賽季目前的成績,以及這一年來你自己感受到的,有哪些很重要的進步跟改變?




今年是我第一年比 VEX V5,跟之前比的 VEX IQ 非常不一樣。VEX IQ 因為是塑膠零件,很容易拆裝,基本上不用思考過就可以開始組;但 VEX V5 主要用鋁,每個接點都要鎖螺絲,組機器消耗的時間多很多,所以通常要先用電腦把機器畫出來。

團隊分工的方面也改變很多,VEX IQ 基本上我一個人就可以做完全部的事情,但 VEX V5 有更多方面,所以一定要分工合作。

這個賽季到現在,我們參加了三場主要的比賽,也拿到很多獎項:

TAI-VEX HS:Excellence Award、Tournament Champion、Skills Champion
PAS-VEX Signature Event:Tournament Champion
VEX Taiwan Open HS:Create Award、Tournament Finalist


3. 你最在行的數學,這一年來你參加了不少的競賽,也包括許多國際賽,請介紹一下過去一年所獲得的獎項,並選一個你覺得最有意思的,分享一下你的心得體會。




以下是我這一年來參加的數學比賽和成績:

袋鼠數學:滿分、世界第 1 名
GJMAT:世界第 12 名
GJMOC:世界第 7 名
AMC 10:傑出、Certificate of Distinction(前 5 %)
AIME:8 分

其中最重要的應該是 AMC 10 和 AIME,其中 AIME 是 AMC 10 排名前 2.5% 才能考的,目前成績報告書還沒出來,所以不確定 8 分是什麼樣的成績,但我已經很滿意了。

4. 語言部分,今年你通過了 N2考試,請分享一下你的準備經驗跟結果。未來一年,會再繼續挑戰 N1 嗎?




我寫了一本 500 題單字的書,並反覆複習,增加了很多單字量,但是考試中好像只有出現一兩次。所以感覺寫模擬考題比較有效,至少知道自己的分數和考試的節奏。

我已經報名了今年 7 月的 N1 考試,就先考考看,沒有通過也可以,之後有空的時候再來用模擬考衝刺。


5. 過去一年,以大型語言模型 LLM 技術達成的 AI,改變了世界,越來越普及,也越來越聰明。請分享一下,在過去一年,你最常用那個 AI 工具,以及應用在哪些方面。你認為,AI 對你做為學生的學習需求上,是有用的嗎?


我主要使用的是 Google 的 Gemini AI,感覺他在各個方面都很強。我在各個方面都會問他,除了 AP 學習上遇到的問題之外,機器人程式遇到的困難、去日本旅遊看到好奇的事都可以問他並得到完整的答案。

以往遇到困難只能想辦法 Google 搜尋,但現在問 AI 比較快也比較準。當然,如果問資訊量比較少的領域,AI 很容易給錯誤資訊,所以重新驗證資訊的準確性也非常


6. 除了學科、機器人、數學競賽之外,你也自行吸收了很多網路上的知識,尤其 YouTube 的各種英文頻道。請選三個你覺得過去這一年,讓你覺得很有意思的影片或者頻道,並分享你的體會。知識、遊戲、攻略、迷因、流行文化、政治歷史等等的都可以喔!




一整年來,我看的影片有很多種類,演算法推薦的影片也會隨時間改變,但是以下是我最有印象的幾個頻道:

Jet Lag: The Game:這個頻道會去世界各地玩遊戲,以整個國家作為地圖,然後搭火車或飛機到達各個地方,我覺得很有趣。順帶一提,他們最新的一季會在臺灣玩。

Luke does robotics:他是一個美國大學生,他會做關於 VEX V5 比賽的影片,我去年就是看他的影片才開始對比賽的策略感興趣的。

Denys Davydov:他是烏克蘭人,以前是機師,現在他每天更新烏克蘭戰況,讓大家比較知道前線的戰況跟局勢的發展。

My 14 Days in Northern Kyushu





For the last 2 weeks, we went to Kyushu as a family trip. We visited Kitakyushu, Nagasaki, and Fukuoka. And this was definitely one of the most special trips I've ever been to.

Our first destination was Kitakyushu City, which was a newly formed city in 1963, which included Kokura and Moji, where we visited. 




After landing in Fukuoka airport, we headed to Kokura to visit our first museum, the TOTO Museum. We were able to learn the history of TOTO. They started making pottery, and eventually turned into the largest toilet manufacturer in the world.

When walking back to our hotel, we stumbled upon a local supermarket and decided to check it out. We found everything super affordable there. So for the rest of the trip, we bought breakfast and snacks from supermarkets instead of convenience stores. 

At night, we ate dinner at Saizeriya, which was a super cost-efficient and delicious Italian restaturant. Everything was pretty delicious. My favorite dishes were the corn soup and the vegetables.




On day 2, we visited Ganryu Island and Shimonoseki via boats. Ganryu Island was where Miyamoto Musashi and Sasaki Kojiro's legendary duel took place. In Pokemon, Team Rocket's Jessie and James were named after the 2 swordsmen. On the island, there are manholes of Koffing and Ekans, which represent Jessie and James. That was where we started playing Pokemon Go again.




Then we went to the other side of the Kanmon Strait, to Shimonoseki. The Treaty of Shimonoseki was signed here to end the First Sino-Japanese War. The decisive Battle of Dan-no-ura was also fought here, which started the Kamakura Period in Japan.




On day 3, we decided to explore Kokura by going to the Kokura Castle and the Zenrin museum nearby, which showed how cartography in Japan evolved. Kokura was where Ino Tadataka started surveying Kyushu, so the museum had a detailed explanation of the whole process. Ino Tadataka was a legend. He managed to draw a super detailed map of Japan over 200 years ago.

Day 4 was super chill, we planned to go to the Kitakyushu City Museum of Peace but it was closed that day, so we just walked around the area and returned early. From a local supermarket, we also bought wagyu and cooked at the hotel. It was super delicious.




During World War 2, the Kitakyushu was bombed heavily by American bombers. Kokura was even the planned target of the second atomic bomb drop because of its huge arms factory. On the old site of the factory, the Kitakyushu City Museum of Peace was built, and we visited it on day 5. We learned the brutality of war and the importance of peace.




In the afternoon of day 5, we went to sing at a Karaoke place. Karaoke in Japan is really rich in songs. Not only do they have Japanese songs, but there were also a lot of K-pop songs and even old Mandarin songs. We had a really good time there.

Our second city to visit was Nagasaki. You might expect a direct Shinkansen line from Kokura to Nagasaki, but due to political and economic concerns, Nagasaki's Shinkansen is disconnected from the main Kyushu Shinkansen line, so we had to transfer via a relay train.

Nagasaki is known for being where the second and last nuclear bomb exploded in wartime. So in day 6, we went to the Atomic Bomb Museum. The whole city was razed and hundreds of thousands of people died from the bomb. Hopefully, Nagasaki will remain the last city to be hit by a nuclear bomb.




After visiting the museum, we walked to the hypocenter monument and the peace statue nearby. There were a lot of statues donated by other countries to symbolize peace. Surprisingly, most statues were from countries in the Warsaw Pact, such as Poland, East Germany, and Bulgaria.




At night, we looked at the night view of Nagasaki from Mount Inasa. It's great to see how the city was rebuilt and continued to developed.




On day 7, we went to the museum and monument of 26 martyrs. About 400 years ago, 26 catholics were executed in Nagasaki by Toyotomi Hideyoshi. The museum showed how christianity developed in Japan over the centuries and how they were oppressed.

Our next stop was a museum for human rights and peace, opened by a local. It showed all of the war crimes the Japanese Army has committed throughout Asia.

In the afternoon, we went to Namco near the station and played Taiko no Tatsujin. For the rest of the trip, we would often go to department stores to play Taiko no Tatsujin. At night, we tried cooking the wagyu again because it was super delicious.

Day 8 was our final day in Nagasaki, we went to the Nagasaki Museum of History and Culture. Nagasaki was where trade and contact with foreigners occured for centuries. It influenced a lot of revolutionaries and ended the shogunate.




Day 9 was our first day in Fukuoka, and we chose to start from Ohori Park and Fukuoka Castle Ruins. The scenery was great in Ohori Park and we walked around the park. Fukuoka Castle Ruins was a great place to look at Fukuoka City.

Day 10 was also pretty relaxing since it was raining. We headed for Tenjin and visited department stores, but we returned early and called it a day.




On day 11, we went to the Fukuoka City Museum. There was a special exhebition, treating our day to day objects as ancient fossils. From the 41st century, things from the 21st century were dug out and investigated. There were even plastic figures of Italian Brainrot animals like Tralalero Tralala, which is an AI-generated 3-legged shark. Maybe people in the future will believe a 3-legged shark actually existed.




Our next destination was Fukuoka Tower. We had a great 360 degrees view 123 meters off the ground. For dinner, we ate at Ichiran Ramen, which actually originated in Fukuoka as well. 

We chose to go to EZO Fukuoka on day 12, which was a building next to the Fukuoka Dome. We first went to Teamlab Forest which was a room with with digital animals on the floor and the walls. We even drew customized animals which was interesting.

On the 4th floor of EZO Fukuoka was the museum of Oh Sadaharu, a legendary baseball player who still holds the career home run record today. I knew nothing about him, but after visiting the museum, I really understood how legendary he was. There was also a pretty big area next to the museum with a lot of baseball-related minigames and we spent a long time exercising there.




We planned to go to Dazaifu city on day 13 but since we were all pretty tired, we decided to fully rest and then go to Karaokekan to sing again. Day 14 marked the end of the trip, our only destination was the airport and went back to Taiwan.

Overall, I really enjoyed the trip. We learned the history of Kyushu and its cities from the various museums. The supermarket strategy also saved us a lot of money and we even managed to eat wagyu twice. Karaoke was also a really fun activity for all of us to relax.


2025-2026 VEX TAIWAN OPEN V5RC HS: Create Award, Tournament Finalist





Last month, we went to the VEX TAIWAN OPEN competition, which is the final major event in Taiwan that is going to determine 3 winners that can qualify for the VEX World Championship. Luckily, we already qualified in the previous PAS-VEX Signature Event. So we don't have much pressure this time.

Just like what we did for other competitions, we held a scrimmage in our lab to prepare ourselves. We definitely learned a lot of strategy and our problems from it.

Since we have already qualified, we chose to use the same robot with some modifications. The autonomous programs and skills strategies were also similar as before.

The first day was pretty easy, there were 1 practice match and 2 qualification matches, along with optional skills challenges. 

Unfortunately, for autonomous skills, blocks kept on getting stuck on our robot. We were only able to get 50 points. The driver skills was better, though our robot had unstable match loading speeds, so we didn't have enough time to achieve higher scores, resulting in 73 points. Overall, these are pretty disappointing scores.

We lost the practice match as our teammate had limited scoring capabilities. Though we soon lost again in our first qualification match because we were entangled with our teammate for the first half of the match. Luckily, we secured the final match of day 1.




Day 2 is when the rest of the qualification matches were played. We had a decent schedule and managed to win all 6 matches while getting 5 AWPs. In total, we have 19 WPs, ranking us 4th on the ranking. We ended up choosing 96969Y, forming the 4th seed.

The round of 16 match and the quarterfinal match were pretty easy. However, we soon met 4253S and 4253Z in the semifinal match. The opponents played really well. Luckily, we pulled off a last second score and descore combo, securing the match.

Finally, we faced 66994D and 17022A in the finals. Both were really good teams and really put pressure on us and we didn't have a lot of opportunities to score. In final 2, we even had our intake getting stuck. After losing the 2 final matches, we ended up as the tournament finalists.




Throughout the tournament, we were interviewed twice by the judges. We explained our robot, programming, strategies, and team management. In the end, we were honored to receive the Create Award.

Even if we didn't get the best results, it was definitely still a memorable experience. This time, since we don't have much pressure, we could fully enjoy the tournament. 

Congratulations to our sister team, 66994D, along with 17022A for winning the tournament. Also congratulations to 66799X for winning the Innovate Award and 66994T for winning the Design Award.

Overall, huge thanks to 96969Y for being our eliminations partner. Also thanks to our sister teams, we were able to learn a lot from each other throughout the practice matches. 

Finally, huge thanks to all of the referees, judges, and volunteers for making this tournament run smoothly.

2025 AMC 10 Oustanding, Certificate of Distinction





This is my first year doing the AMC 10. This blog is going to be a documentation of the scores and some future plans.

Before the test, I wrote a historical test every week. I probably did 50 of them. I thought I improved quite a lot, but it turns out that tests from 40 years ago were way too easy that I could even get 150 points sometimes.




There are actually 2 tests this time, a 10A and 10B. I decided to take both so I don't mess up. For 10A, I was super careful and double checked my work. I ended up completing 18 problems and left the rest blank, scoring 118.5 points. 




Having a pretty nice score already, I went for speed mode on 10B and wrote a total of 21 problems. Unfortunately, I made quite a lot of mistakes and ended with only 15 correct, resulting in 96 points.




With the score I got on AMC 10A, I got the Certificate of Distinction and qualified for the AIME competition which is a way harder competition.

This year's honor roll of distinciton for AMC 10A requires 136.5 points, which is incredibly high. And the honor roll of distinction cutoff for AMC 12A is 150 points, which is quite unbelievable.

Overall, I'm quite happy with the results, and now I'm preparing for the AIME coming up and possibly the AMC 12 test for next year.

2025-2026 TAI-VEX IQ: Match Emcee Volunteer





Five years ago, I came to AST with my sister to participate in our first-ever VEX competition. We were inexperienced rookies back then. Five years later, we returned to that same gym—but this time, my sister served as the Head Referee and I was the Match Emcee.

The growth has been incredible. Five years ago, there were only 20 teams. This year, we hosted 25 Middle School and 33 Elementary School teams over two days, including teams that traveled across the sea from Hong Kong. Seeing TAI-VEX and the local community grow so quickly is truly inspiring.

To prepare for the event, I spent time studying the game manual and the specific names of scoring objects. I wanted my commentary to be accurate and to properly represent the teams' complex strategies.




Throughout the weekend, I was able to observe the teams closely. Nowadays, top VEX IQ robots feature complex pneumatic systems, complete sensor integration, and high-level optimizations. But beyond the hardware, I saw the same passion and excitement that we had half a decade ago. These teams spent months building, strategizing, and practicing, just like we did.

To the students competing: Whether you went home with a trophy or not, you have already won because you chose to build and not consume. The skills you learn in VEX aren't just about mechanisms; they are about the engineering process, the ability to work under pressure, and communicating effectively with your teammates. Through successes and failures, you are getting closer to true "Excellence," which is something that can't be found in a plastic trophy alone.

Overall, it was an unforgettable experience. Thank you to AST for the opportunity to be an Emcee—it was truly an honor. Thanks also to the referees, scorekeepers, judges, scouts, field-resetters, and the tech team for making the event run so smoothly. I would have been much more nervous if it weren't for all the friends around.

There are certainly still improvements I can make as an announcer, and I look forward to working on those. Hopefully, in the future, I can find even more opportunities to talk about robotics.


2025-2026 PAS-VEX Signature Event: Tournament Champion





Last month, we went to the PAS-VEX Signature Event. This is the first Signature Event I have been to. Tournament Champions and the Excellence Award winner will qualify for VEX Worlds.

Competition Introduction


This year, there are 72 teams from around the world that participated in this event, including the best teams from Taiwan, Vietnam, China, and other countries.

This event lasts 3 days in total. The first day was relatively low-pressure since there were only practice matches, which is why we chose to do the team interview and most skills matches on the first day. The second day is crucial as 6 qualification matches are played, almost confirming the qualification rankings. Finally, on the third day, 2 extra qualification matches are played, elimination alliances are selected, and the elimination rounds to determine the tournament champions are played.

Pre-competition Preparations


Before the competition, we did a lot of preparation. For 2 weeks, we basically practiced every day to tune our robot and practice driver and autonomous skills. Our robotics lab also hosted a small scrimmage with 11 teams. That was where most of our tournament strategies were developed.

Other than the match preparations, we also prepared decorations and gifts(stickers and cookies). We also familiarized ourselves with the team interview, as it is an important part of the competition.

Day 1


Finally, it was competition time. On the first day, we quickly did autonomous skills: we ran the stable route, and it worked, giving us 74 points. After that, we moved on to driver skills, running it three times. Although a few mistakes were made and we couldn't control the upper center goal, we still ended up with 83 points. This was below our expectations, but still good enough to secure us the 3rd place in skills.

Another important part of day 1 was the team interview. The interviewers were pretty nice, and we introduced basically every aspect of our team, including team organization, the notebook, robot details, programming ideas, and our strategies.

Finally, the 2 practice matches. We won both of them, including a match against a really great team, 50922T.

After the day, we were still busy testing the autonomous skills for day 2 and scouting our teammates and opponents. I slept at 12am, which was very late because we had to wake up at 6am the next morning.

Day 2


For our first qualification, we almost got the AWP but failed to load on the left side, though we still won. In the second match, we successfully ran the Solo-AWP strategy, getting the AWP, but ended up losing the match because one of our intake disconnected, completely preventing us from scoring.

On our third qualification match, our teammate 86254B was really good, and with them, we got an AWP and the win. The fourth match was quite unfortunate as both of our autonomous vehicles were unsuccessful and ended up losing auto. Luckily, we still won the match.

The fifth match was great because we got the Solo-AWP and ended up winning the match. For the sixth qualification match, we unfortunately failed to load on the right side during auto, so we didn't get an AWP, but won the match.

At the end of the day, we were ranked 6th on the qualification ranking, not low but not the highest. So we might be unable to choose our desired teams. At night, we looked at different possibilities and came up with a list of teams to possibly cooperate with.

Day 3


The seventh match was really important. We were against 78181A, one of the best teams. We ended up successfully running the Solo-AWP strategy and getting an AWP, though 78181A did so as well and even outscored us, losing us auto. Luckily, our teammate and I both did well and won the match. This match boosted us to the second ranking.

The last qualification match was very unfortunate since a block from the other side of the field flew here and disrupted our auto, cost us an AWP, though we still won the match. Ending qualifications with us in 2nd place.

Then comes the alliance selection part. Had the 1st place team, 50922T, chosen 66994T, our alliance with 66994T would be broken. Luckily, they didn't do that at the end, and we were able to fight the eliminations with 66994T.

Our strategy worked quite well, as we won the round of 16, quarterfinal, and semifinal matches with pretty big score differences. 

Final 1, both of our autonomous ran well, and we won the auto bonus. Our teammate 66994T really dominated the right side long goal and the center goals. We faced some difficulties but ended up winning the left side long goal as well, taking the first final match with a 47-point difference.

Final 2 was a lot trickier. We lost the auto because the autonomous changed the strategy, and our auto didn't work well. The driver period was also really close, but 66994T secured 2 control zones, and we slightly won the left side in the last second. Winning by a narrow margin of 27 points.

Before the eliminations, judges came to us and asked for a second team interview, but we had to play the eliminations, so we didn't have time. After the finals, our second interview was cancelled, and we didn't end up with any judged awards, probably because we already won the tournament. It was really sad since we had spent countless hours writing the engineering notebook, but at least we qualified for VEX Worlds.

Conclusions





After the competition, we made a recap video with the best parts of each match. Feel free to check it out.

Huge thanks to all 3 of my teammates, our alliance partner 66994T, every team we have cooperated with, and every team participating in the event. Also, thanks to the PAS volunteers who made this event possible. Thanks to our coach and our sister teams, who taught us a lot throughout the season. Last but not least, parents who supported their kid to play VEX.

Through the 3 days of intense competition, we have gained a lot more than the award alone. We faced challenges, like the motor disconnection on day 2, or the auto malfunction in the final 2. They really tested our ability to stay calm under pressure. Luckily, we were able to end up winning the tournament.

We still have the Taiwan Open Competition before VEX Worlds, so we still need to keep improving. But I'm extremely happy and grateful for the tournament win.


第 22 屆 IMC 國際數學競賽臺灣初賽 一等獎







這個比賽是我第一次參加,是新加坡主辦的數學比賽,在初賽考得好的話可以去複賽,而在複賽表現不錯就可以去新加坡比決賽。

初賽的話有 25 題選擇題(每題 10  分)跟  2 題計算題(25 分,會看計算過程)。比較神奇的是雖然考卷大部分是中文,但選擇題會有 5 題用英文出題。

我這次的成績是 275 分(總分 300),所以選擇題都對,然後有一題計算題不會寫,我記得好像是我最不擅長的幾何題目。英文題目的話不會到特別難,因為我很常寫的 AMC 歷屆試題都是用英文寫的。

最後我得了一等獎,IMC 的獎項分組蠻特別的,分為一、二、三等獎和優異獎,一等獎是前 8%。

理論上我三到四月會要再去考複賽,如果能進前 35% 就可以去新加坡決賽,聽同學家長說辦的還不錯,感覺會是一個很特別的經驗。

第 62 屆奧林匹克團體賽 個人賽金獎





上個月我跟數學教室的三個同學去參加奧林匹克團體賽。我雖然今年還可以報名國中組,但是因為數學教室湊不出四個人,所以我就跟其他三位高一的同學在一隊,而其中兩個也是去年團體賽的隊友,所以還算熟悉。

奧林匹克團體賽有分四節考試,首先是以個人為單位的競速賽和思考賽,競速賽要在 20 分鐘內寫 15 題,時間壓力很大;思考賽則是有 40 分鐘解 8 題難題。接著是以團體為單位比的接力賽跟團體賽,一隊在接力賽會分成兩個兩人小隊,每個小隊的人要接力寫題目,如果前面有失誤後面就會寫不出來;團體賽則是四個人一起寫同一份考卷,難度也偏高。

我們在數學教室其實有練習過,結果是接力賽全軍覆沒,但是團體賽能在 15 題中答對 8 題。我個人在練習的時候大概能在競速賽寫 8 題、思考賽能對兩三題就不錯了。

比賽當天我運氣不錯,在競速賽穩穩地寫完 9 題,但是後面的沒時間寫就用猜的,後來發現後面其實有些題目很簡單,很可惜沒有時間寫到,之後可能不能在前面花掉太多時間。思考賽我竟然會 5 題,算是運氣很好,但後面的毫無頭緒。

接力賽算是比較可惜的部分,因為時間其實也很少,所以我們沒有得到很多分數。團體賽我們則是合作的還不錯,寫了很多題。

最後我拿到了個人賽金獎,而我們隊因為接力賽跟個人賽分數比較低,所以沒有進到前 30%。不過我們現在都才國三跟高一,之後還有機會嘗試。

總之今年的奧林匹克團體賽是很特別的體驗,我也很感謝我的隊友們,合作的都很好,之後成績一定會越來越好。

2025 GJMOC 銀獎 全球第 7 名





我最近考了今年的 GJMOC 考試,而我這次是全球第七名,獎項是銀獎。

GJMOC 是印度舉辦的線上數學競賽,考試不像 GJMAT 分三大部分,GJMOC 是直接給你 25 題,每題 4 分,總分 100 分。時間是兩個小時,所以一題平均可以寫 5 分鐘左右。

我是今年才知道 GJMOC 獎牌是看分數決定的,不是像其他考試一樣是照排名給獎,這次我考的是 8 年級組,銀獎就是 50~70 分,因為這個考試真的不簡單,所以我很滿意了。

考試的整個過程都很緊張,因為有些題目真的很難,最後我就把我會的十幾題寫完而已,即使會的全對好像也沒辦法拿到金獎。

GJMOC 是個很有趣的比賽,線上考試也很方便,之後希望可以持續進步,挑戰拿到金獎或是繼續提升排名。

TAI-VEX Push Back HS: Excellence Award, Tournament Champion, Skills Champion





Last weekend, we went to the American School in Taichung for the TAI-VEX event, which is the first major competition for our Push Back Season.

Our team, 66994B Unicorn Puncher, was lucky enough to bring the top 3 awards home: The Excellence Award, Tournament Champion Award, and the Skills Champion Award. This was a fun and enjoyable journey.




For the skills challenge, we actually practiced for around 2 weeks prior to the competition. 

The autonomous skills code was mainly written by me, and I made sure it was as consistent as possible. Our first attempt scored us 60 points. The second and third autonomous attempts didn't go nearly as well due to problems with our intake system.

For driving skills, we have a bigger margin of error since we can control the robot. Though sometimes control zones can be tough to get. But finally, driven by my sister Jin, we ended up with a nice 84 points.

Our match schedule for qualification matches was extremely good. We were paired with our sister team, 66994T, once, and paired with 78181A, one of the top teams, twice. Unfortunately, though, we didn't manage to get the AWPs on these 3 matches because we had problems scoring into the lower center goal.

Overall, we won all but one match and got 1 AWP. This ranked us first in the qualification ranking. There are lots of great teams in this competition, but we chose our sister team, 66994T, as our elimination alliance partner because we have had experience working together.

Our first challenge was during the semifinals. We had 66994D, our other sister team, and 1791V, a very consistent-performing team, as our opponents. They did a great job using side wings to de-score our blocks. Luckily, we managed to swing the match back after intense battling around the long goals.




We fought a best-of-3 series of matches for the final matches. Our opponents were 17022A and 78181A. The matches were very competitive and had us stressed. We ended up winning 2 matches in a row. Our strategy was to defend and hold onto the long goals after securing the advantage in the autonomous period.




However, performing well isn't the only criterion for the Excellence Award. Teams also have to perform well on the Engineering Notebook and the Team Interview. Luckily, we have prepared for the notebook since the start of the season, and we have practiced the interview to clearly demonstrate our design processes, robot, programming, strategies, and team management. Finally, we are honored to receive the Excellence Award for this year's TAI-VEX.

We have found a few problems with our robot. So we might either improve our robot or make an entirely new robot.

The next competition for us is the PAS-VEX Signature Event in December, which has 3 spots for the World Championship. So we should prepare hard and aim for the awards.

From the start of the season, I have learned a lot from VEX, including programming concepts, strategic thinking, and communication. I'm also very excited about the future competitions and the great teams and robots from everyone.

JLPT N2 通過





最近日檢 N2 的結果出來了,而我也很幸運地通過了,這篇部落格會簡單介紹我的準備過程、考試感想跟未來的規劃。

我在言語知識得到 34/60 分、讀解 33/60、聽解 43/60,總分 110/180,而及格的標準是每科至少 19 分,而總分要超過 90 分,所以我算是低空飛過通過分數。




準備的部分,我主要是靠「新日檢完勝500題N2:文字‧語彙‧文法」這本書,每天寫 15 題,把不會的單字跟文法寫在筆記本,然後每天複習前幾天的單字。寫完一遍這本書後我又花了一個月複習一遍,詞彙量有明顯變多。不過這些單字跟文法在考試出現的比例好像沒有很高,大概幫我多答對了不到 5 題吧。

考前幾個禮拜我也會寫幾回模擬試題,除了體驗時間壓力之外,也讓握稍微熟悉考試會考的題型。模擬考的言語知識我通常能答對 60% 以上,但是在實際考試可能比較難,表現差一點。聽力反而是我在模擬考的時候覺得最難的部分,可能實際考試的時候運氣比較好,分數高了一點。

下一個目標應該是 N1 檢定,但感覺 N1 會難很多,最近我可能會先拚機器人比賽,之後有空再來衝刺 N1。如果要準備 N1 的話,可能會要買不只一本書來讀,模擬考也要多寫。

總之這次考試通過有一點運氣成分,不過也讓我學會準備一場考試,之後如果要準備重大考試就會比較有信心。

14 天日本關東、東北旅行





這次我們去日本的關東和東北地區,主要是在東京、福島和仙台周邊,前一個禮拜是住在上野去東京的各個區玩,後一個禮拜則先後去福島和仙台並用 JR PASS 搭 JR 去周邊的地方。




第一天我們從成田機場降落,去飯店放好行李後就去第一站,琦玉縣的川越市,我們主要的目的地是川越的 Chiikawa 專賣店,從車站走到目的地要走大概半小時,還好沿途有很多店家,也有江戶時代風格的建築。




第二天我們規劃去淺草寺看雷門,下午去晴空塔和樓下的購物中心(也包括 Chiikawa Land)。淺草寺的人很多,當天又非常熱,所以蠻辛苦的,不過能看到雷門和淺草的五重塔也算值得了。




中午我們就決定去晴空塔了,順便在那邊吃午餐。晴空塔的購物中心蠻大的,我們逛了 Chiikawa Land 跟 Pokemon Center,也意外看到了一家叫「戰國魂」的店,裡面有各種日本戰國時代武將的周邊商品,我買了一頂德川家康頭盔的帽子,之後去比機器人比賽可以戴。




逛完樓下的購物中心,我們就買票上去晴空塔了,晴空塔是目前日本最高的高塔,可以看到整個東京的景觀,天氣好的時候甚至能看到富士山,可惜我們去的當天沒辦法看見,不過看到東京的各個知名景點還是很壯觀,包括淺草寺、東京鐵塔、東京巨蛋和各大副都心。




我們去的時候,晴空塔剛好有跟名偵探柯南合作的活動,為了宣傳柯南的新電影,整個天空迴廊都是柯南的人物,除了看風景之外也能看到喜歡的角色。




第三天我們早上先去上野站附近的東京國立博物館,因為下午還要去其他地方,所以我們只有逛到本館和東洋館,在本館還有看一個講解日本動漫的影片。博物館的建築都很好看,不過因為當天很熱,所以沒辦法很有效的欣賞。

下午我們去秋葉原,主要是去看 Animate 和唐吉訶德,不過因為對大部分的商品沒什麼興趣,而且人多到有點擠,所以我們最後買的不多。

晚上,我們搭電車去東京車站,目的是去東京車站的 Chiikawa Land,雖然這間應該是我們去過最小的,但人的密度應該是最高的,選對地點真的很重要。

本來打算要直接回上野,但是我們發現日本橋就在附近,所以我們就走過去,不知道是不是因為是市中心,GPS 訊號很不準,所以花了比較久的時間走過去。




現在的日本橋是 1911 年重建的,但是從四百年前的江戶時代就有日本橋了,日本橋是全日本道路的原點,那邊還有里程碑顯示往北或往南多遠會有哪些城市,很有歷史。




全日本第一家百貨公司——三越百貨,也是在日本橋旁邊開的,這棟百貨同時很高級又很有歷史感,裡面有一大尊佛,門口也有兩隻獅子,跟完全商業化、現代化的百貨公司很不一樣。




第四天,我們去靖國神社和旁邊的遊就館,靖國神社供奉的是明治維新以後在戰爭中死亡的所有日本軍人,而遊就館是講述這些歷史的博物館,即使某些戰爭是不正義的,這些軍人也只是為了國家犧牲的可憐人。




下午跟晚上我們去新宿,先去關東最大間的 Chiikawa Land,接著不小心進去了一家紀伊國屋書店,發現看書蠻有趣的,所以之後我們每次經過書店就會想進去看看。






第五天開始,我們買了 JR PASS,所以就開始去東京以外的景點了,第五天我們去的是栃木縣的日光,目標是去看日光東照宮和德川家康的墓,蠻有趣的是,廟裡面竟然有擺一隻鋼彈,跟工作人員詢問了之後才知道原來那隻是德川家康的鋼彈。




第六天,我們去宇都宮的大谷地下採石場遺址,採石場在地底,裡面很冷,也很大,非常像地下城的感覺,很神奇又很壯觀的感覺。附近還有一個大谷觀音,但是因為覺得會太晚而沒有去看。另外,宇都宮有新的輕軌路線,但因為方向跟大谷採石場相反,所以沒有搭到。




第七天,也是我們在關東的最後一天,去大宮站旁邊的鐵道博物館,從大宮到博物館要搭一個叫「琦玉新交通」的列車,這條路線也有四十幾年的歷史的,不是很新。




鐵道博物館超大,還有很多體驗開列車的遊戲,但是因為還要抽資格,覺得有點麻煩,所以就沒去玩。本館有很多列車的 1:1 大小模型,可以坐在裡面體驗當幾十年前的乘客,南館則有比較多歷史的資料,包括一些技術上的介紹。




晚上我們去附近的琦玉新都心看看,從車站二樓的出口出去就可以從天橋走到三間 Cocoon City 百貨公司,吃甜點、逛了一些店之後就回飯店了。

第八天應該是整趟旅程最廢的一天,我們早上從上野去福島之後就躺在飯店了,頂多晚上去附近的商場逛一下而已。

第九天我們從福島先搭新幹線到郡山,再轉磐越西線道會津若松,磐越西線的車是四人四人座的,每一個座位區是兩個座椅和另外兩個座椅面對面的那種,因為在郡山沒找到四個都空的位子,我跟姊姊只能去坐陌生人對面,而對面的是一位 78 歲的阿伯,目前還有在工作,他很友善地跟我們對話,雖然我們日語還沒很流利,但還是能大概溝通。

阿伯知道我們是台灣人之後就開始講他來過台灣的哪些地方、吃過哪些美食等,很有趣。他還跟我們推薦會津若松附近的拉麵店。不過到站前 20 分鐘,阿伯開始講關於宇宙電波、外星人之類的話題,很好笑。




到會津若松後我們就搭公車去會津若松城(又叫做鶴城),這座城在戰國時代換過很多城主,最後則是跟將軍德川家有密切關係的松平家控制,後來在明治維新的時候是幕府軍的重要要塞,打了很久的戰役,甚至有很多青少年戰死,非常殘酷。

第十天因為原本沒什麼規劃,就去了第九天經過的郡山,我在來日本之前根本不知道有這個地方,但郡山市已經是福島縣人口最多的城市了。我們找了車站的景點,決定去郡山科學館,這個科學館沒有自己的一棟建築,而是在一棟大樓的最上面幾樓。可以從郡山的最高點看到風景。




我們運氣不錯,去科學館的時候因為是平日早上,幾乎沒有人,可以體驗在月球上跳躍,第一次跳那麼高真的有點可怕。另外,科學館也有可以讓遊客一起做實驗的,我們參加了兩場,分別介紹磁鐵跟單擺,對學生來說是很好的學習機會。




看完科學館,我們在地圖上發現附近有 AEON TOWN,類似 outlet 有很多店家,那邊很多停車位,應該主要是讓人開車去的,所以我們從車站附近走過去的時候一直覺得走錯路,看起來不像是會有店家的地方。不過實際上店家都很好逛,我們也買了不少東西。




第十一天,我們到了仙台,也是我們最後一個待的都市,第一個目的地是地底之森博物館,從仙台站可以搭捷運到,這個博物館有很古老的土壤層和一些樹木的殘骸。看完後我們就回去仙台站看 Chiikawa Land 跟 Pokemon Center Tohoku 了。




第十二天,我們去看伊達政宗歷史館,不過歷史館不在仙台本身,要搭車去松島,可以順便看日本三景的松島海岸也不錯。從松島海岸站走到博物館的路上我們還吃了號稱松島布丁的布丁,其中有一個叫做伊達政宗口味的巧克力布丁,也還不錯吃。

伊達政宗歷史館除了介紹伊達政宗的生平之外,前面還有東北的名人,其中就包括後藤新平、新渡戶稻造等對台灣有巨大影響力的人物。




伊達政宗是日本戰國時期的東北地方大名,因為右眼看不見,所以又被稱作「獨眼龍」,實力不錯,可惜出生的時代太晚,而伊達政宗歷史館把他從出生到晚年的重大事件都用蠟像做得很真實,算是很用心的博物館。




第十三天,我們去了東日本大震災傳承館,裡面詳細地記錄了 311 地震和福島核災的歷史,有將近兩萬人因為這場大地震死亡,真的非常沉重,希望福島早日恢復。

在傳承館旁邊,有舉辦一個社區交流會,因為門上寫說所有人都可以參加,所以我們就進去了,裡面除了玩一些遊戲之外,還可以試開無人機,很有趣,志工也很熱情,我們闖關成功後還送我們很多零食,非常感謝。




在日本玩的最後一天,我們去了仙台最有代表性的伊達政宗騎馬像,在青葉山上,旁邊還有仙台城遺跡,除了能跟伊達政宗拍照之外,還能看到仙台市,甚至能看到仙台大觀音。




隔天我們就搭飛機回台灣了,這次雖然沒遇到 F-35 戰鬥機,但是飛機到台灣上空的時候有成功拍到台北 101,雖然沒有很清楚,但還是很神奇。

這次旅行應該是姊姊去讀大學之前最後一次全家出國了,而我也真的玩得很開心,也買了很多娃娃、扭蛋之類的,我覺得非常值得。

現在回想整趟旅程,我覺得都很好玩,東京的大都市真的很方便,去哪裡都可以搭電車很快就到,但東北比較輕鬆的感覺也很好,這次旅行的大部分行程其實是前一天才想的,但還是很感謝媽媽的規劃。
