<p>All colleges that commit to meet 100% of need, i.e., the entire Ivy League, MIT, Stanford, Duke, Chicago, and a host of top liberal arts colleges. If your family truly has so little income, need-based aid can be very generous. Harvard (and, I believe, several other schools, but I don't remember the details) has committed to financing 100% of its cost loan-free for students from families with less than $40,000 income.</p>
<p>Don't be distracted by all the focus on merit aid on this site. For many relatively well-to-do families, there is a huge gap between what these colleges think the family should be able to pay and what the family thinks it is able to pay, so merit scholarships become key. For families with as little income as yours, need-based aid is absolutely fine -- often better than merit aid at the 100%-of-need schools.</p>
<p>And you should be extremely proud of your record -- there isn't any school that you are not qualified to attend. That doesn't mean you'll be accepted everywhere, of course, because lots of other kids are qualified, too. </p>
<p>One thing you may think about is looking at some good liberal arts colleges where the school has good science facilities and faculty, but they attract fewer science-oriented students than elsewhere. (I'm thinking of Wesleyan, in Connecticut, for one.) The combination of your background, gender, and interest in science would be a plus for you there.</p>
