Fun facts about me

I love sitting in on lectures: I have audited courses from PhD level physics (quantum condensed matter) to psychology (human motivation, cognitive, etc.), computer science, and more. I aim to audit one course per semester, no matter how many actual courses I'm taking for credit that semester, and I can usually keep auditing that class until almost the end :]
By the end of my undergraduate degree, I will have completed 64 courses, whereas a typical student only needs 40 courses to graduate. This is because I have two majors (honours physics and major physiology), while most BSc students at McGill only need one major to graduate. The trade-off is that I took more courses every semester and I took an extra year, but it is totally worth it because I get to learn BOTH how nature works and how the human body works!
I aim to learn a new sport every year (since 2015). I do this to stay healthy and make new friends, and now I can play over 10 sports!
I have been an undergraduate teaching assistant for over 13,000 students. This is practically half of McGill's population!
