Think this through, what will you do if you turn down the job, AND don't get any accepts this year????
Your MCAT score is < the 10th %ile for Wayne State. If you're a MI resident, your best chances will be with MSU, Central MI, Western MI and Oakland-B, plus MSUCOM.
IF you get shut out, then yes, retake the MCAT, and add more non-clinical volunteering, especially with those less fortunate than yourself. Get off campus and out of your comfort zone.
