Just think of the logistics involved with following up 350 sets of extra curricular activities. Personally, I don't think they check. The most they could possibly do is ring up your referrees and/or principal and ask them to give an impressional description of you. What they are looking for is something at least pseudo-genuine, so even if you have to lie your ass off, don't lie about the stuff that matters, ie. you SHOULD want to be a good doctor, and you SHOULD want to help people, even if not directly. I mean, even if you want to go into medical research, I'd assume you have some sort of inclination towards making discoveries beneficial and relevant to health and mankind.
If not, then why not just go into research per se? Quantum physics...or nuclear arsenal, perhaps...
