UBC is fucking sweet. I'm in second year engineering at UBC and I'm having a blast. Whistler pass including tax was about $425, which is a really good deal. it's available to all post secondary students in bc and washington i think. busses run from the residences to whistler and back every friday/saturday/sunday, and you can take transit (FREE) all the way to grouse. campus life is pretty good, with something to do all the time. residence fucking rocks, always a party to go to if you're in totem park residence... plus 3 bars on campus that have consecutive student nights. monday is open mic at koerner's, tuesday is karaoke at the gallery bar ($8 pitchers of beer), and wednesday is student night at the pit, which is the closest thing ubc has to a club (ie - it has a dancefloor and a dj. it's definitely still a pub though).
i think the admission average for science is somewhere around 90%. more like 75% for applied science (engineering), but eng is way harder than science (i don't get it either...).

SFU (simon fraser university) pretty much blows, unless you enjoy living in a concrete prison with the highest suicide rate at a university in bc (maybe all of canada, i'm not sure).
