Hi, I'm Barry ๐Ÿ‘‹

Grade 9 student. Math, bass, and a workbench full of problems.

I love mathematics and play guitar and bass. This site is where I keep every contest and project I'm working on โ€” one focused workbench per goal.

About me

I'm Barry, a Grade 9 student. Math is the subject I keep coming back to โ€” proofs, problem solving, and competition style mathematics. Outside of school I play guitar and bass, mostly rock and funk grooves.

This site collects the contests and study projects I'm working on. Each one is a self-contained workbench: notes, drills, practice problems, mock tests, and a plan. Static HTML, hosted on Cloudflare Pages.
