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。
