Sorry, let me elaborate.
The person I quoted was asking about the frequently mentioned "fact" that Vanderbilt has the "happiest medical students" in the country. Basically, where does that statement come from?
This was cited at least as far back as when I interviewed, and I wouldn't be surprised if it went back further than that. I was told by someone (whom I've since forgotten) that this fact came from the pooled answers of medical students who take a senior AAMC survey. Every senior medical student in the country, as far as I'm aware, is given the opportunity (it's optional) of taking this survey. Many of the questions have to do with how your experience was during your four years, if you were ever mistreated, etc. I just took this survey a few weeks ago, as I'm a senior student.
Honestly, I have no idea whether this is actually true, though I have no reason not to believe it. I'm guessing it was specific to whichever class took that survey though, and without any updated info, I can't claim that we're still number one
Anyway, I suppose there's always a chance your class could be full of monumental douches, and it would be worthless trivia! I doubt that would be the case though -- my classmates are pretty fantastic. I've enjoyed four years here, and I think most people would. We'll see how I feel after Thursday (and about 8 hours from now)...
