I'm Barry, a Grade 9 student in the US. The subjects that stuck for me are math and, lately, machine learning — both reward you for being precise about what you actually know vs. what you've been told. Outside school I play guitar and bass, mostly rock and funk.
Why this site exists: I noticed that when I "study" a topic by reading, I forget it in a week. When I write it down for someone else to read, I remember it. So every contest I prep for gets its own workbench here — notes I wrote in my own words, drills, practice problems, mocks, and a plan with real dates. If it helps another student, even better.
