Wow, I was going to stay away from this thread on principle as I've typed this very response so many times my keyboard is wearing thin.
Dont listen to anyone on this thread. Ok, maybe some, but most is terribly wrong and misguided advice. There is nothing wrong with taking some classes at CC even if your at a 4-year.
Man I hate repeated myself, OP, can;t you just search a little bit? Seriously.
So, I took most my pre-reqs at CC then at my 4-year I took both physics at a CC while at 4-year......lets see....I got asked about it never at any interview either year I applied. Never. Not one question and I just received three pre-match MD acceptances. If your wanting the "prestigious" "top tier" school, then maybe, but a great state or private med school is not going to care.
Been there, done that, going to med school. You just need to do whats best for you and forget the rest. What pre-med students who are applying or haven't even yet applied think about your application is irrelevant. What they think adcoms will think is irrelevant. Just do your courses, make A's at the CC, keep your grades up at 4-year and your fine.
Oh, and learn to search on SDN, please?
