Cornell, Columbia, Penn

Hello, I am a HS Junior right now and want to ED to one of these schools. I have posted a chance me thread here: http://talk.qa.collegeconfidential.com/what-my-chances/1993616-chance-me-columbia-cornell-northwestern-penn.html#latest. I would like to do comp sci/math toward finance and am wondering what school would probably be the best for this.
