About
Aside from math, music is a big part of my life, and I can be seen walking around Toronto vibing to Taylor Swift. I have been enjoying singing and playing the violin for many years and have been in all sorts of ensembles, including an acapella club.

I do anywhere from 1-6 hours of math a day depending on how motivated I am at that moment. I also do CS (this one's definitely a work in progress), play guitar, beatbox, snowboard, and talk about cheese slightly more than the average person.

About
Looking forward to competing at SLC again this year! I've participated in a variety of other competitions in my school career, including the Bow Seat Ocean Awareness Art Contest last year, and doing the Junior Breakthrough Contest three years in a row, submitting a high effort digitally hand drawn animation each time. Furthermore, I've participated in business and other STEM competitions, including attending the national FUSE business competition in eight grade. In my free time, I enjoy volunteering at a hospital and utilizing my marketing skills in general. :) "Know all the theories, master all the techniques, but as you touch a human soul be just another human soul ." -Carl Jung

About
I tend to gravitate towards the social sciences: history, geography, economics, politics, and the like. Maybe that's because most of my family are MPs. "Geography has made us neighbours. History has made us friends. Economics has made us partners. And necessity has made us allies." - John F. Kennedy, Address Before the Canadian Parliament
