Your record is excellent. Your SAT score, as it currently stands, is within the middle range for schools already referred to such as Amherst, Brown, Cornell, Hamilton and Northwestern. As you move forward you should, as suggested by warblersrule, further specify what you would most value in terms of your general college experience and realize that some schools with acceptance rates of ~25-30% and higher should be considered as part of your research. I agree, btw, that there is no reason to assume that schools such as Harvard and Cornell operate with substantially different admission criteria.
