I got rejected by 10 of the 11 UG schools I applied to, and the one I was accepted at I actually got waitlisted at first
The most obnoxious letter was definitely from UNC,
Some people just aren't good enough"
I agree arhodg, its fantastic motivation to keep those things around, I've still got all of mine.
I'm thinking of applying to UNC just for the hell of it, and then if I (presumably) get in, sending them a withdrawal letter saying "some schools just aren't good enough"
