"To say that pre-med courses at a community college are on the same level as university courses is ridiculous. I know I'm probably gonna get flamed for saying that by the few who believe they are, but let's be serious here. Community colleges cannot offer the same resources that a university can. Also, community colleges take everyone who applies. They are in the business of granting people course credits. If they made their courses super hard, lots of people would fail, and no one would continue to sign up for the courses (thus sending the college to bankruptcy). At accredited colleges/universities, there are more than enough students to go around, and there are plenty the admissions offices turn away every year who wait in the wings to be accepted down the road. As a result, such institutions are able to make the courses much more difficult."
I'm not gonna flame you for it...and I took classes at a regional extension of a state U so maybe you won't see it as parrallel to a Community College, but it sure felt like a CC to me. Because it was an extension the transcript came from U State, so I have no idea what admissions committees think of CC's.
I had some great classes there, better than some at my U later on. One that was so rigorous that only 6 of 30 survived. That instructor is still there doing the same thing to poor unsuspecting students. The school is still in business. I also had some lame classes. For 100 level classes I honestly don't think you are guaranteed to get a better education in a large auditorium filled with 18 year olds who don't give a darn. At a CC, despite open enrollment, its often people who are genuinely interested in being there and have a clear socio economic interest in doing well.
At the U later on I had some great rigorous classes, and I also had classes that people were just breezed through.
Another strength of a CC is its open enrollment, you work with a much broader spectrum of people than at a U and way broader than a private college and that will make you a better MD down the road. Maybe adcoms see this, maybe they don't.
Grades in Upper level classes at a U following a CC will be a good indicator of quality, and student ability. Again, maybe adcoms see this, maybe they don't. You seem to know more about what adcoms like than I ever will, but I got into 2 of 3 schools I applied to, waitlisted at the other and I started out at an extension school. The bio and chem I learned there served me pretty darn well on MCATs.
So AmyBass..., my advice is to talk to the prospective community college and see if they have students who have taken the path you aim at. If they have, that is probably a good sign. If not, well maybe Bones 2008 is raising an important concern.
