I was accepted to Dartmouth this year (and I interviewed on the last day so don't worry if you get a later interview date, it's not just for waitlist spots). My GPA is 4.0, 33 MCAT, hailing from a no-wheresville school that was not located in the New England region. I am hardly flawless and took time off to work after undergrad. I thought the whole application and interview was stress-free. The student body seems very happy (I saw the extent to which this was true at second look). Reviewing the potential incoming class list I didn't think that they were too biased towards New Englanders. There's a lot of people from CA, TX, etc. They have a very strong program for U.S. health policy. If you are interested in international health their program is fledgling--at best. These were just my impressions from a couple of visits.
