I have no problem with CC coursework; there are some out there that can be as rigorous as any four year school. And Adcoms do not have a problem, in general, with CC coursework being done prior to finishing at a four year school. The majority of med schools in MSAR have no ban on pre-reqs at a CC (Baylor being the one exception I can think of off hand).
LizzyM has expounded on avoiding taking the pre-reqs at a CC while you're at a four year school...it gives the appearance of avoiding the weeding courses.
That said, I have a few Adcom colleagues who look down on CC coursework. I have to arm wrestle them at Adcom meeting time to salvage decent candidates they'd otherwise wait-list.
