What are my chances at these colleges?

Your resume is very impressive! NYU is very competitive though. My bet is that you will make it in. Their average ACT score for incoming freshmen this year was a 32. Your SAT score is right in the middle (of their accepted range of students). But, if you want to stand out, try to increase it, if you already haven't tried to. Have you taken the ACT? If you're more math oriented, that test will be better for you... it was for me. You extracurriculars are spectacular! You've def. covered that part of it- very impressive. Just make sure your essay is AMAZING... surprisingly, colleges give A LOT of weight to that. I'm not to sure about Bernard and Wellesley. I'll find out and answer again! ;) Hope this helps!
