I don't know too much about it but I don't think so.
You may want to check with the schools you are applying to for their policies concerning deferment, if they even allow it in the first place (some schools don't).
You do have to fill out the AMCAS form again, applying to that single school. It's their way of assuring you don't apply to other schools (without their permission) in your deferred year and then dump them. I've heard you don't have to pay the fee again, but I'm not certain it's true. Anyone else know?
