I applied to Wisconsin-Madison, BU, UIUC, and Rutgers as well. I was accepted to Wisconsin, rejected from BU, and not yet heard from the other two. I might accept Wisconsin instead of Columbia. Limited stipend (covering only 4 year and not enough for living in NY) is one of the reasons.
I got into the Columbia University. But just like @sunluck21 I was waiting for UChicago's decision, and I found that someone just has posted the admission result.. UChicago was my priority and I put all my efforts and hope into the application. Disappointed..
