looking around this site I realize the obvious, and that is that when you write 15 apps, you are bound to make one or two mistakes. not everyone does, but appearntly many of us do, i know i did. now i dont know what the right course of action for you is, but i will say that i think this forum is a gathering point for the all of the world's most stressed and over achieving L1 wanna-bes. i think there is a tendency to take things too seriously around here. i might very well be wrong when i say "dont worry about it, im sure a little mistake like that will not be noticed, and even if it will, will be ignored" but then again, i know as much about what goes inside that committee as anyone else here, which isn't much at all. my point, take it easy, you might be urged to send in flowers and an apology letter, and prepare to be auto-dinged from every school you ever applied to, but i have a feeling that like most advice LSD, you should take it with a grain of salt.
