BACK ON TOPIC:
The reasons that caused me to choose UF were primarily reputation, cost of attendance/living in the area, and performance on national examinations.
1. Reputation: Every time that I've spoken to a physician, when they found out I was going to UF it was almost as if they became a different person. Many of them noted the excellent quality of student work being presented at national research conferences as well as the ability of students to transition into the role of an intern seemlessly. From my understanding, residency directors are aware of the success that UF grads have on the wards, and take this into consideration during their decision-making process.
2. Cost of attendance: UF is a state school, and apartments around the school tend to be extremely cheap to live in. When you've got undergrad loans and med school loans staring you in the face, CoA becomes a very big factor in my opinion.
3. Performance on National Exams: As Neatloaf has already stated, UF has traditionally had very high scores on national board exams. You may say "Hey, I'll work hard for the boards on my own." Yes you will. However, the fact that UF bases its curriculum off the boards makes things a whole lot easier when you finish 2nd year and start studying for the boards. I'd much rather have a whole lot of review material to go over rather than seeing much of it for the first time. It's really nice when professors teach what you need to know for the boards, rather than droning on for an hour about their research on novel stem cell therapeutics in stage I clinical trials.
Oh, and the football is pretty nice too (not so much this year, haha).
