JLPT N1 通過





最近我考 N1 的成績出來了,而我今天我想分享日文檢定 N1 的準備過程和一些心得。

考試時間是七月初,而我是從五月底開始準備的。其實我因為一開始覺得 N1 非常困難,所以想要逃避,但後來爸爸鼓勵我努力試一次,畢竟我六月空閒時間比較多,如果幸運考過的話以後就不需要煩惱了。

根據姊姊之前考 N1 的經驗,寫考古題是最有效的方法,所以我也是用這個方法準備。

我第一次寫考古題,文字語彙和讀解大概都只對一半,所以我去問了 N1 讀解滿分的姊姊,我覺得最大的改變是心態,仔細讀過的話會發現題目沒有這麼難,只要能找到關鍵的句子就能夠得到答案。經過大概五回考古題,我在讀解部分進步到可以對八成左右。

至於文字語彙的部分,我覺得真的比較難短時間內練起來,只能透夠持續寫題目來學更多單字和文法。聽解的話也蠻困難的,但我覺得能夠在紙上很快記下重點幫助很大,尤其是後面重點很多的題目。

考試當天,我記得文字語彙很難,幾乎都是我沒遇過的單字,所以有點害怕沒拿到 19 分而不通過,還好最後運氣不錯,有拿到 26 分。讀解的部分倒是蠻簡單的,我大部分的分數都是在這裡拿到,最後得到 53 分。聽解我記得很難,大概只有三分之一的題目是我確定的,最後得了 33 分。

所以三個項目加起來我得了 112 分,只比通過標準 100 分多一點。如果我少猜對幾題可能就要年底重考了。

總結來說,寫考古題幫助很大,但我實際考試運氣也不錯,才能驚險通過。我想要感謝提供經驗跟建議的姊姊,幫助真的很大,還有父母的堅持讓我有動力在知道考試很難的狀況下努力準備。

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.
