To those that get dinged:
If you don't get dinged by any of the schools you applied to, you didn't apply to good enough schools. Remember, you are trying to maximize the value of the school/s you DO get accepted at, which by definition means you'll miss on some. Don't stress, just focus that frustration into energy for the essays for subsequent applications.
I submitted on the 1st for Columbia ED, also applying to Stern, Kenan Flagler (UNC), Darden, and deciding between Fuqua (Duke) and Wharton.
