1) I think you mean New Hampshire - might wanna take a quick look at your secondaries to make sure you didn't make that mistake in there too
I actually enjoy it up here a lot for several reasons. One - I found myself not very distracted while studying during my first two years because it's more isolated but if I wanted to get out of Hanover, it was really easy to go visit friends down in Boston since it's a two hour ride. Also, I really like the college town feel and I went to a school very similar to Dartmouth for undergrad. During 1st and 2nd year when you have more free time (or I guess a more flexible schedule), it's a fantastic area to get out and do some hiking, swimming, running. Plus, I know that I'm most likely going to end up in a city for residency and probably the rest of my career so now was a nice time to get away from that and really focus on studying medicine.
2) Most certainly. I'm not sure exactly why Dartmouth does this so much more than other schools but they definitely do like having non-traditional students with unique backgrounds aka careers outside of medicine for >5 years before deciding to come to med school. Definitely is cool to learn about their backstories and it enriches the class as whole IMO. That being said, I think every med school has that to a certain extent.
3) I think they do but honestly, I'm not sure if it's much different than other schools. There are curriculum changes occurring largely because of feedback from students. Different admin people handle different years in school (aka 1st year vs 2nd year vs 3rd year clinic) so it may vary year to year but overall, I think they have been receptive. For example, I'm not sure if it's permanent, but they were definitely responsive to students wanting more Step I study time as this past year it was 7/8 weeks compared to 5 weeks previously. Also, 4 MS2's are voting members on the admission committee with other students able to help conduct interviews and attend admission committee meetings.
