Chances at Dartmouth/Brown?

Well, you already know you've done a great job. I don't know what more they could ask for, except maybe a higher SAT score (for example: more than 25% of Harvard's students scored an 800 on their English and 790 on math). It also matters if you took the hardest cles that you could have (at number 1, you probably have). But you've obviously worked hard, and your essays will probably be great from your background info. chances: very good. Don't stress. Congrats in advance.
