About

Welcome!

I’m Richard, a Year 11 student currently studying at Bangkok Patana School with enthusiastic interests in math and competitive programming (C++) and algorithms, and I participate in the yearly UKMT maths challenges and weekly AtCoder Beginner Contests, and despite my vertical monitor power I don’t seem to do great often, at least compared to my classmates . Most of the content here will be on those subjects, perhaps about things I recently learnt about, or an interesting puzzle to solve. I’m also proficient at playing the piano (just got distinction on ABRSM Grade 8) and killing little green men in Kerbal Space Program. My friends all tell me to go touch some grass…

Finally, if you have any questions or suggestions, drop me an email at contact@xuyuanxia.com (I do not have a phone, nor do I have social media) and I’ll try to respond as soon as possible. Enjoy reading!

Things I’m learning/working on:

  • Preparing for the AIME / British Mathematical Olympiad Round 2
  • Taking AoPS’s MathWOOT (Worldwide Online Olympiad Training) Level 1
  • Chopin’s Ballade No. 1
