just a couple of things to think about before you make a desicion:
1) don't listen to just me
2) ask ?'s and not to the admission ppl. they're in the business to sell the school. i agree they're awesome, but they are not a good guage of how the other ppl are in that school. ask the ppl who have to deal with bu everyday, meaning the students. ask if the apex is worth it. if they had any complaints.
3) bu is about money. they keep accepting more and more students when there's no chairs for the ones we have now. apex btw is a program to get students out of the school, so others can use the classrooms. it's not to 'gain clinical expereinece'.
4) interviewers for bu, don't even have their dental license. there's something seriously wrong with that.
5) boston is expensive. studio around school will be $1100. and that's cheap. you're not going to want to commute. plus the commute is subway and bus. the busses here suck, esp the #1.
6) if you want to come to bosotn anyways... think harvard or tufts. both are close to subway stops.
i sound bitter as heck don't i. sorry i'm tried. good luck.
