I would recommend also doing something related to medicine or anesthesia in the next year while you decide what path to pursue. There's plenty of AA's with healthcare experience and it certainly can't hurt. Admissions also takes into to account where you went to school. So if your university wasn't as competitive as some of the top state schools then that may be contributing to your problem. Try calling the school or going in person and asking what aspects of your application could be strengthened.
