Hi, I'm Barry ๐Ÿ‘‹

I'm a Grade 9 student building four workbenches โ€” one per contest I'm chasing.

Math is my home turf โ€” I keep coming back to it because a proof either works or it doesn't, and that honesty is addictive. Outside class I play guitar and bass (rock, some funk). On this site I keep public notes for the contests I'm preparing for: HiMCM modeling, USAAIO, and the digital SAT. Public because writing it down forces me to actually understand it.
