Please don't take this the wrong way, but perhaps since you are even asking that question - your intentions in medicine didn't come across clearly in the interview. PA and med school are totally different with different goals. If PA works for you as a back-up, perhaps you aren't dedicated enough to medicine, and maybe this came through in your interviews. It may have contributed to you being waitlisted. Maybe you should do some thinking about what you really want? With your stats, I would be reapplying to medical school if medical school is what you want. If you aren't sure about that anymore - please don't apply to any type of school til you are sure what you want.
Well, you have a 3.95 and 39 MCAT. Oh man, please do a me favor and apply to MD schools. I mean, your school selection is too top tier.
Why you didn't apply to middle and low tier med schools ?
...these people truly had a passion for the PA profession...
from what i have seen in the ER, PA are sort of like residents. they have to confirm with a physician before they do anything. lookig at your numbers, you should def concentrate on med school and not PA as a back-up. have hope.
