Agree with all the previous posters thus far. Listen to FourMoreYears: he's in the loop on this one.
I got as far as an interview at DMU last year, for some insane reason (new job) turned down an interview at LECOM and withdraw my applications to ATSU and KCUMB. I still kinda hope to hear that I've been pulled off the waitlist for DMU

although it's fairly unlikely at this late date (May 12th).
DMU really liked my clinical experience as a PA. They weren't so keen on my underwhelming undergrad science grades and borderline MCAT. They liked my outstanding PA grades (I kicked it into gear and plus I loved what I was doing). If I didn't make it in this round they suggested I retake my low grades and take an MCAT prep course & retake. I may still do that, or I may become a happy PA. For now I'm enjoying teaching PAs and learning that way.
You might ask, didn't all these thoughtful folks on SDN warn me of all this before I spent thousands of dollars on apps & interviews? well, they did, but I generally have to learn everything for myself, the hard way. If you are not opposed to learning from someone else's experiences, though, I would advise that you 1) retake any science prereq that was lower than a B ad 2) retake MCAT for a score no lower than 25-26, and take a prep course if you need to.
Good luck!
