First, I must say that I think OSU is a great school, and you will get an excellent education there. However, having gotten the disclaimer out of the way, I want to give a couple more of my opinions on OSU.
You mentioned the flexibility of OSU's curric. as a strength. I personally saw it as one of their biggest weaknesses. Yes, it's cool to do PBL IF you are interested in it, and IF you are selected for it. And as far as independent study goes, that is a possibility at any school - it's called not going to class (I'm a pro at it). But I think the biggest fault in the three pathway deal, is the fact that it causes huge divisions and rifts among the students. The groups seemed pitted against one another (to me), and highly critical of each other. I witnessed this first hand from a friend in the LD path who spent an hour bitching about the PBL "slackers," and the ISP "freaks." My class at UC is a much more cohesive group.
Also, the Anatomy in 12 weeks thing is another weakness (in my opinion). I also initially regarded that as a strength, but am SO glad we had year-long anatomy. First off, if you've ever taken a condensed course, you know it makes long-term retention an issue. And anatomy is so full of memorization, that I think it would be 12 weeks of hell. And I loved gross, it was my favorite course. It was nice to have gross lab 2-3 times a week. The labs break up the monotony of an all lecture day. Plus, as I said before, our curric is integrated, so you are actually learning the physiology and the micro anatomy at the same time as the gross anatomy. This just makes more sense to me. Plus, we have 4 person teams, not six!!!
BUT, in the end, everybody should go to the school where they will be most happy. It's 4 years of your life, and believe it or not, you can have fun during those four years. Both cities are full of things to do (even though I love my home town of Columbus more). And to the Cleveland lover out there, don't even get me started on "The Mistake By the Lake!"
