Strangely enough, I also went to WashU (though a few years older than my fellow bears). To answer your question OP: Yes, I found it overwhelming. The thing that overwhelmed was this: from a very young age I wanted to do medicine (due to taking care of my disabled sister and becoming interested in the physics and biology of the human body), but never had a taste for the sheer competition involved. Many of my fellow pre-meds were grade obsesses, and, like, "study obsesses" -- spending full weekends in the library, spending so much time on their work that it was just distasteful. It overwhelmed me because the other pre-meds frankly just turned me off to wanting to pursue that path. Further, I was not mature enough to set such a high goal and adhere to it in such a competitive environment. I was more interested in going to the gym, partying, and chasing skirts. So, it was a combination of the extremely intense pre-med apparatus and student population that I found extremely overwhelming. I remember one of my roommates in the dorm (who just recently graduated from Vanderbil med) -- really nice kid, who claimed to "love" basketball and knew the stats of all his team's players, but looked so severely awkward actually holding a ball - I mean, I couldn't even call him on it because it would have been so sad. When I was out playing ball on weeknights with friends, he was literally getting gray hairs studying. This was the kind of kid I was comparing myself to everyday: was I studying as hard as him? did I want *it* bad enough? Like I said, I just wanted to do medicine to maybe be an orthopedist or a geneticist, and the intensity of the pre-med life really just turned me off. That all being said, your mileage def may vary. I found it extremely annoying, however, YMMV.
