hey, you! I'm an OOP (out of province Canadian) who got into McGill as well! I'm posting on the SDN forum because I also got into Hopkins and I'm trying to decide between the two (while still waiting on UofT and UBC). Still trying to decide, but you sound awesome, potential-concert-pianist!
John Hopkins, huh. Well, it sounds as if you can't possibly make a bad choice Let me know if you decide on McGill. I would love to get to know some people before orientation. It'll make it all seem a bit less intimidating.
