<p>I don't think being premed at MIT is any more work than just being a normal MIT student -- many of the premed requirements (physics, calculus, biology) are General Institute Requirements, so everybody at MIT takes many of the premed classes. (I think because of this, there's not a very intense "weed-out" of MIT premeds -- unlike most other schools, everybody is taking the "premed" classes.)</p>
<p>Actually, I think the general opinion at MIT is that being premed is easier than many other sorts of things MIT students do. I have a friend (who just got into a bunch of awesome MD/PhD programs) who is premed and still has time to do both cheerleading and volleyball and be an officer in her sorority.</p>
<p>MIT itself doesn't have a medical school, but I've heard of many people getting clinical internships at many of the hospitals around, like Mass General. (There's a particular program, the Externship program, which matches current students with alums in many fields over the January break -- many of those alums are doctors.)</p>
