<p>Since you are female have you considered the all female colleges like :Wellesley, Smith, Bryn Mawr, Mount Holyoke. I have heard these are all especially good. I have also heard some good things about Agnes Scott, Scripps and Mills.
But the first for I have heard are really nice with financial aid (although some of them do not call themselves need blind, but “need aware”). I head some of them also them take quite a few transfer students every year.
I have heard that Smith and Wellesley are especially good in the sciences, and I read Smith just got a new science building so that might be of your interest. I think you should definitely check them out.</p>
