I second toughdecision's question: of those of you committed to attending... any specific reason other than "It's Harvard" or "It's the best medical school in the country" ?
I am fortunate for my luck this cycle, but I feel like I owe it to myself to examine my options carefully instead of blindly doing what USNews tells me to do.
I am also deciding between schools and here are some of Harvard's plusses:
1) Hospitals - so many great places to train and do clinical electives. Main rotations at the Brigham, Cambridge Health Alliance (if you don't want to do the main ones at a big research hospital), MGH, and BIDMC. Plus there is McLean (psych), Children's, Roxbury VA, Faulkner etc...
2) Location - Boston is a great city. It is close to both beaches and mountains. Lots of little squares and neighborhoods. Museums, symphony, good walking areas. Also is it not built as tall as New York so for me, it feels like a more comfortable place to live.
3) Peers - I like that the class size is larger than some other med schools. I guess I'll maybe start to glimpse the class character at revisit.
4) Available faculty/research labs/potential mentors - Related to the long reach of the HMS's arm. Since there are so many affiliates, I feel like I could really do some digging and find some good mentoring in any field.
5) Name - I spoke with a senior physician at one of the major hospital affiliates and he really believes that HMS grads are helped by their school name. This has probably been discussed at length on SDN but I'm more likely to believe it coming from someone who has been involved in many cycles of the match and who picks subspecialty fellows every year.
6) Price - thanks to their middle income initiative, Harvard is likely to be the cheapest option for some students. Basically, you get a $24,500 loan per year and the rest is grants. It is a "full ride" in the sense that your tuition is nearly free.
Of course the weather is really crappy and the big city hospital (Boston Medical Center) is NOT run by Harvard, but by Boston University. Some people might like a closer knit academic community (Harvard University in general is known for the autonomy of its departments and for its decentralized approach). Also, I don't think that the preclinical years at Harvard are the best around, but I have a feeling that a lot of people end up teaching themselves no matter which school they go to.
I went to the undergrad and have lived in Boston for a few additional years so that's my take. Good luck to all the deciders.
- if Harvard lives up to its name, I'm sure that there'll be many cool people at revisit weekend to meet and decide to room with. Sounds like the best option to me
