I was just accepted to a school that I declined interview to. Not going to name the school, but I just recieved an acceptance packet (my name is spelled correctly) from a school that I had previously politely told that I did not have the funds to interview at though I wish that I could. Good times.
Accept their offer but tell them politely that you do not have the funds or the time to attend. Perhaps four years from now they'll send a diploma - with your name spelled correctly!
since you weren't really counting on that acceptance, are you willing to transfer that acceptance to my name? who knows...they might not even find out.
Is it from an American MD program? If so... then... wow. You must be so impressive that you don't even need an interview.
