I'm looking for some insight about the atmosphere at each of these schools. I really liked the sense of community at Dartmouth and also the setting. However, I don't know if I can pass up the opportunity to go to Harvard. What is the community like at Harvard? And as it is a larger university, what are class sizes really like? And is it necessary to study 24/7 to do well? Any and all information about these two schools would be really helpful. Thanks!
