Off the top of my head, I retook maybe 5 or 6. But they were all C/D-->A. My last 30 hours were a 4.0, it is just my undergrad that is killing me, I guess. I graduated with a 3.5, but that was only because I had repeated some classes where only the last grade was taken, and TMDSAS reminds you of all your bad grades. PS was read by quite a few people and I was told was very good. LORs were from my post bac program of teachers I was close with, including some I helped design lesson plans, etc. I also had an MD letter from my research position, of which I'm going on almost 2 years. Not to mention my hospital job. I was hoping that would get me some interest, but it did not. So I am currently deciding between reapplying or applying to the masters program.
