To answer your questions: The schools were definately competitive. I had a pretty good background because I went to a college that is ranked very high. My GPA was decent...around a 3.3 or so. However, I completed all of my pre-requisites before applying and I had a 4.0 in all of my pre-reqs. My GRE scores were good, but not phenominal. I had a combined score of approximately 1150 on the GRE's with a 5.5 on the writing section. I also did a great deal of volunteer work at Massachusetts General Hospital, which I think helped a bit. I think that the real advantage that I had were my recommendations. I work as a research assistant and my boss (who is a highly educated Ph.D. and J.D. from an ivy league school) wrote me a raving recommendation. I do really feel like they looked at the whole package, and not just one specific aspect. I hope that this answered your questions!
