I got my first response last week from the only school I applied to that had a December deadline. I was accepted for the Applied Math PhD program at Rensselaer Polytechnic. I can't even begin to describe what a relief it is to know that no matter what else happens, I have somewhere to go in the fall. (a decent program, at that) The rest of my deadlines were either yesterday or don't even come up until the end of the month, so I don't expect to hear from anyone else until February at the earliest.
