I say screw maryland. if I remember correctly, they had an early deadline of 10/15 and they can't get the invites out in time! i'm actually going to email them now to close my application b/c I really don't want to go to a program that handles their application process like this. they had to be the latest program to snend invitations for an early dec interview.
anyways, this brings up a new topic to consider, if you are a strong candidate and now have enough interviews. and some programs such as MD have yet to send out interview invitations for a date you know you don't want to go to, you may consider helping you fellow applicants by closing your application prior to invites being sent instead of just waiting to decline their offer. this way someone who would have been on the waitlist will get a 'first wave' invite. then again, there aren't too many programs left, but I have 3 in this situation which I will let them know. it will actually be nice to say: I reject you. I wonder whether they will still send me rejection letters just for the sake of it.
