I think your chances for acceptances at Davidson are excellent if you apply ED. It’s probably more of a high match for RD. Penn, Wesleyan, and Cornell are all reaches. Emory and Colgate are in the high-match/low-reach range. Others are matches, I’d say. If you want Davidson, go for it. I think they love those who love them. I suggest applying to at least one other school with either rolling or non-binding early action, while keeping some backup choices.
