hey,
i transferred to ucb from a jc down south. some of the classes at my jc prepared me very well, others not so much. i don't know where you're going to jc, but i hear laney has a superb bio program. i'm not sure if it's laney or vista but previous professors from cal left there positions here to go teach over there. i'll tell you one thing, the biggest difference was the COMPETITION. cal kids are super competitive and it might break you at first. my first semester i didn't do so hot(3.0). it's not that i didn't study, i just didn't have berkeley figured out. now i do, and the funny thing is, my gpa at cal is better than at my jc. just study your ass off cuz these two years go by in a heartbeat. plan your schedule intelligently. don't take more than two core mcb classes a semester. figure out when you're gonna take your mcat and schedule your classes to coincide with your mcat so you won't have forgotten by then. that is, try to take your mcat right after you finish you major sciences(physucks, ochem, bio 1a). and one last thing, don't be scared of berkeley. we have dumb students here too.
