What are my chances of getting into Yale, Penn or Duke?

Oh, I forgot this. I definitely depend on financial aid, like most people from my country that go to college in the United States. Here people don’t save money for college, so unless you’re a millionaire, if you’re brazilian you can’t afford going to college in the US if you don’t receive an almost full financial aid. But I don’t necessarily need a full financial aid from the university, because there are programs here that help us afford college abroad.
