Who got in to the nursing program with a lot of C's?

It's going to depend on your how competitive your program is to get into. If there aren't a lot of applicants, the minimum requirements might be enough to get you in. If there are a lot of applications for a limited number of seats, the seats are going to the ones to did the best.

I got into my community college program with mostly B's and C's. Obviously it depends on program requirements though.

It's really going to depend on your particular program. I live/lived in an area were nursing is a highly competitive major and people ge bent out of shape over the pre-reqs, which are more cut-throat than the actual nursing programs. Most of the nursing programs I applied to required a minimum of 80% score (B-) in all pre-req coursework, but a couple did allow "C" grades in non-required general electives, provided overall GPA was still high.
