I'm in the same situation with columbia. I got waitlisted on my birthday (omgwtf) and I've been patiently waiting to hear back from them. The thing is, I think they keep the chances of getting off the waitlist a secret. The letter I got said I would basically have to wait to see if someone dropped on in July, but when I called Dr. McManus, he said I "could get in anytime after Jan 15th." Maybe that was just a sneaky way of saying your chances are pretty low. I dunno. I'm gonna love life in the mean time.
