I don’t know too much about Cooper Union; however, Columbia seems like a very high reach just because of your EC’s. I would suggest varying them more, maybe add a sport and add depth to the finance side by finding an internship or something of that sort. For UChicago, I think you definitely need to try and get your SAT up.
