Oh really? Ok. I'm a little impartial, because I've been around Hopkins all my life, and I know a lot of the people, and so I know them more for their personal qualities rather than their academic ones. I'd say that some of Hopkins's overlaps would be WashU in St. Louis, Tufts, Northwestern, and perhaps NYU. To me, it doesn't seem like the kind of place that draws on the overacheiver, top of the class, 800 math/verbal, super kids that the Ivies and some of the other draw on. Hopkins looks for regular people who happen to be smart.
If that puts it in the top 20, then I'm actually suprised. I... just never knew Hopkins like that.
PS: Its library is really cool. I was there this weekend looking for books on Nigerian Theatre, and they have those awesome movable shelves that I like.
