<p>I know you said you were looking for a school in the northeast...but other than that I think you should really consider looking at Washington University in St. Louis (I realize other people mentioned it...but wanted to emphasize it)...It's (in my opinion) the perfect size (about 6,000 undergrad.), very nice campus, good suburban location, friendly student body etc. ALSO>>> this school is very flexible when it comes to majoring...double majors are very common (30%, i think), and it is extremely easy to change between the different undergraduate schools (business, arts, arts & sciences, etc)...students I know who have done it say all you do is sign a sheet of paper, and you're done. Anyways, I've gone on long enough, basically the school just really encourages a variety of interests and academic pursuits, and I'd encourage you to check it out!!</p>
