What colleges should I be able to get into?

You're in good shape, but you'll need to recalculate your GPA on a 4 point scale, unweighted for grades 9-12. I'm sure your guidance counselor knows how to do that, and if not there are definitely formulas floating around. Community service is great, honor roll is important (especially if you can get into honors societies), and your class rank will be taken into account. For NYU and the ivies, you'll need outstanding SAT/ACT scores. You should also keep in mind that many of the ivies do not have undergraduate business programs. If you're looking for the top undergraduate business programs (many of which may surprise you), I've enclosed a link. If you're looking for other things to give you an edge, you should try to get a few extracurricular activities beyond volunteer work. If you can get leadership positions, such as editor of the school paper, VP of the conservation club, etc. that would really improve your chances. Hope this helps!
