hey jasmine ! congrats on getting into mcmaster, you're going to love it
don't be nervous about meeting new people, there are going to be so many people in the same position as you ! Are you going to welcome week ? I strongly suggest you do, you can buy a macpass which allows you to get into all the events -
http://studentsuccess.mcmast er.ca/...ation-kit.html -during welcome week youll meet a ton of new people, possibly future best friends!, and even though your not in res you can still enjoy all the events and meet new people - just be open to meeting anyone and everyone (during welcome week it seems like youll meet a million people) and youll be set !
im not in the commerce program, but i can say that health age 1bb3 was an interesting class
good luck with everything and dont hesitate to post more if you have questions
