I might disagree with Finch. Don't go to a college based on whether or not you think it will help your chances to get into med school. Pick a college based on what you want from college. I don't mean to sound harsh or condescending, but it's not guaranteed that you will want to go into medicine after having had a few years of college, so why base your college selections on that?
I did not go to Colorado College, but I can tell you a few things about it, being from the area: Colorado College is a great liberal arts school, although finch is right in that there are bigger name liberal arts schools out there. It is probably much stronger in humanities than the sciences, but I can't say that for sure. The location is either unbelievable or really poor, depending on what kind of person you are. Colorado Springs is a gorgeous city, right at the base of Pikes Peak--if you like the outdoors, and the mountains, you'll love it here. If you want big city life, I can think of few places worse than Colorado Springs, especially if your political orientation is left of center. Colorado Springs is one of the most politically conservative cities in the country (although you probably won't feel it as much being on a college campus), and forget about night life. True, it's only a little over an hour to Denver, but you probably won't want to be making that drive ALL the time.
There are a few other folks on here from Colo Springs, so maybe they can chime in (hopefully, not in the form of flames directed at me 🙂 )
Lemme know if you want any more info from me. For the record, I went to a very small liberal arts school (not CC), and loved it (although I did struggle at times). I really think that smaller schools have a lot of advantages over bigger schools (and yes, I know there are drawbacks too). For me, I couldn't imagine taking a class with hundreds of other people, which you'll have to do if you're a premed at a big university. Most of my classes were maybe two or three dozen people, tops, learning from the professor, not a TA. You won't find that at any big university. And, I like the fact that at my school there wasn't the super competitive academic spirit. For me, that's a good thing! Also, the advantage of going to a smaller school if you do want to look at it from a med school point of view is that you'll most likely get much better LOR's, from professors who actually know you, than at a bigger school. The biggest drawback is that small schools can get really claustrophobic--you might get really sick of always seeing the same people every day.
Anyways, that's my two cents.
