I agree with Alex, it's been a good overall experience. Of course there's the BS that comes with any school. But the school did a good job of picking good people to be your classmates. We have a good variety of people, and we all get along really well. Should've seen some of our post-test parties!
The big difference from undergrad to med school is the fact that you aren't competitive at this level. Because everything is straight scale, there's no reason to be competitive with your classmate. So we all try to help each other all the time. Ultimately, the goal is just to pass and if you do well... it's icing on the cake.
