my major was economics. which i think gives me a leg down in pbl, since there's no structured curriculum and i have to look stuff up all the time. there are 144 students in the first year class. i think the number stays the same from year to year with the pbl program. there are 6 cells of 24 students. a large class but you become very close with your cell mates!
the admission process is alittle untraditional, kinda like pbl. you're interviewing THE school to see if it's the right match for you. not the other way around. everybody who interviewed with me got in.
i think people take pbl very lightly not knowing what it's all about. pbl isn't for some people, but if it is...pbl is a great way to learn dentistry. my advice to you is ask students (1st and 2nd years mostly because they're not a 'pilot' class) and sit request to sit in a session and see how it really works with a REAL case.
eva in admissions is really cool. i had never said a word to the woman and during week 3 i stopped in the hall and she knew my name. which kinda was nice, you know. she's very helpful.
good luck to ya!
