HAPPY 18TH BIRTHDAY TO GUANZHONG YANG!
Read his birthday article: An Imperfect yet Unregrettable Journey
2025 May:
1. Mathematics Monthly 2025.5 available now! As Guanzhong Yang has already graduated from high school, this is his last Mathematics Monthly that has been written and published. Great appreciation for those who read his Mathematics Monthly!
2. CAIE AL Economics Handouts available now! Good luck to those waiting for the CAIE result!
3. An article summarising Guanzhong Yang’s high school life will be published on June 18th to celebrate his birthday!
4. The UI of this website will be changed once Guanzhong Yang starts his university life!
2025 March:
Initiated π Day activity! The activity involves 3 brilliant circle-related questions, and the top three participants providing the most brilliant explanations will be awarded the textbooks, reading notes, and lecture handouts that Guanzhong Yang organized!
See the question page through 2025 π Day Activity!
2025 February:
1. Better UI! You can now find your materials much more easily!
2. More materials available! Including 100-page reading notes for university-level textbooks, Mathematics Journal 2025.03, 200-page BMO and AMC handouts, 30-page Oxbridge Interview Preparation Handouts, and so on.
3. Re-organized mathematics puzzles! Now, they are organized into different documents so you can read them more effectively. If you want to see the dated version, click on “Mathematics Puzzles“.
4. Removed “Vlogs” and “Travel Diaries” sections and re-defined “Tutorial Videos” section since I, Guanzhong Yang, want this website to be my academic website only. If you do want to check through some funny videos or articles, click on “Vlogs” and “Travel Diaries“. If you want to see PCT voluntary online lectures held by others, click on “Tutorial Videos“. In the future, those sections will no longer be updated, but you can still access them through the links.
5. Nothing meaningful, but I love Rouon Aro! (See him on the top-left corner!)
