i feel your frustration skim2....my stats are similar (3.73, 3.71 sci, 25/20)....
I've run into quite a few people on the interview circuit who've gone to Harvard for interviews & from talking to them they didn't seem to have particularly "unique" or amazing backgrounds, so I don't know what the deal is.
And it's true, UConn does do better than them on boards and as far as entering stats go several schools are higher or very similar (UCLA, Washington, Columbia, UNC, etc.)....from what I heard from a girl who interviewed at Harvard last week, they interview about 80 people out of their pool of 750 or so and offer spots to 40 of them to fill their class of 35....
If you're looking to specialize, Penn, Columbia, & UConn (that i know of) all place grads into specialty programs just as well, if not better, than Harvard...
