I know we're supposed to retain one acceptance, and drop the rest... I am holding acceptances at a few MSTP, but have been waitlisted by my top choices (accepted MD only). My question is, do I have to drop these offers to avoid the possibility of having my other acceptances rescinded after May 15th? Does MD/PhD waitlist count as a "waitlist", or will they look at the fact that I'm accepted already to MD? Confused and a little worried - thanks in advance for any insight.
