I haven't read but half of the responses to this subject, but wanted to go ahead and post my opinion to this topic anyway. I, unfortunately, am not fond of community college coursework. Anyone can get an A in these courses because there is little or no competition, and/or the professor or curriculum at the school does not push the student.
A state/private school will truly test yourself as a student. I have a very difficult time believing that community colleges give you the same learning experience as your state or private school. All you CC go-ers feel free to disagree with me, but it is my understanding that staters are much more challenging. Sadly enough, applying to dental school seems to be all about numbers these days; so I suppose CC coursework would be fine in terms of getting into dental school. However, be prepared for a rude awakening during dental school. I know for a fact the work load between state schools and community colleges is like night and day.
