Some people just aren't meant to be pharmacists. I can tell you there are a few in my class that I don't think will graduate. Also, some people enter with an AA from a CC and think they can hack it. Some most definately can and do and work their butts off, but some people just can't. It's really hard to start this kind a program without really being challenged before. I can say from experience, some people drop out for personal reasons and some just don't have what it takes. I also think each program is different, I've heard of some programs that will pretty much force-feed the info so that everyone passes and some are very strict. I think there are a lot of factors.
