I am probably going to U of Maryland college park, mainly for financial reasons (as a Maryland resident I would get the in-state tuition benefits) and close proximity to my home. They have highly ranked math and physics departments and I know one of the bigger professors there personally, so it looks like the best choice overall. I applied to MIT and Princeton as well just to see what would happen, and now with this ISTS finalist status my chances of getting accepted are very good, but there are still the money and distance issues. I will be looking at these two for the graduate degree, but don't need to worry much about going to a high-profile school for undergraduate stuff.
