I applied to the accelerated B.S./M.P.A program with UMDNJ and got in!!!! I don't know how many applicants there were, but as far as I know, only 11 people for the joint degree program got an interview, and they only accepted 5 ppl.....
But if you apply after undergrad then i think you will have a better chance cause my P.A. program is accelerated and required me to apply at the end of my sophomore year as an undergrad O_O
