My middle child a daughter was a 15. As you probably know at Dartmouth you go by you year of graduation. She had to choose between Dartmouth, Amherst, Bowdoin,Williams. Only you know you and if you want a college that emphasizes undergraduates over graduates. She wanted a school that was undergraduate focused. She finally felt that Williams was too isolated and small. Hanover is small and isolated, but not as much as Williamstown. I can say from numerous visits that the vast vast vast majority of students enjoyed there time at Dartmouth. There is no perfect school and there are unhappy people everywhere, but most loved Dartmouth. However she felt she could have been happy at Williams.
