Not trying to put you down but I will tell you my not successful story... I took my MCAT on September 11 last year, applied anyway, and by the time I got the secondaries in, most people were already getting accepted. I got a 31 on my MCAT, a not so bad score, but my GPA is a little lower than yours. I was rejected and never got an interview, sadly. What I did afterwards: applied to a SMP, got in and now will be attending Georgetown for the 2014-2015 academic year. This year I am trying again, with everything in, trying to finish all secondaries before August and with better credentials because now I have Georgetown under my belt...
Its up to you but sometimes waiting a year will guarantee your entrance... what if you don't get the score you want? You have to chance to sign up again and study harder... That's my input... hope it helps
