Boston University, , University of Wisconsin–Madison, University of Rochester,which I should accept?

These are all great schools. You can go to a top 20 graduate school from any of them - none of them is necessarily better than the others for that.

That’s not what that means. The fact that 86% of people graduate in four years does not translate to an 86% probability that any particular person will graduate in four years. The individual probability of graduating in four years is related to a variety of factors that are particular to each individual’s characteristics and needs, and is going to be different for every person.

Boston may be a better city for finance internships. I’ve heard really good things about Madison as a city as well. It also depends on the atmosphere you want.
