I'm nervous too. I have been reading a book on ethical cases in medicine so I have an idea of the thinking that goes on when deciding any kind of ethical case (medical or non-medical). I am looking at my primary application and personal statement. I am also thinking about the most likely questions that would be asked in an MMI format. These include Why SUNY upstate, why do you want to become a doctor, what are the positives and negatives of medicine, why did you not choose other health professions, health care reform questions. Also, practicing your interview skills will help during stations that one could not prepare for anyway (e.g. acting station)
