I applied late the first go around and never got off the waitlist. This cycle i applied very early and interviewed Oct 31st at meharry only to be waitlisted this cycle as well. After being waitlisted I sent them like 4 or 5 new science classes that were A's and told them about my job in the hospital. I'm guessing my med school interview was my mhs interview at the same time. There is no specific mcat or gpa score and for the most part it is at their discretion. My advice is just to apply regularly even if you think your chances are slim and keep working to improve yourself as an applicant each cycle via mcat, diy post bacc, research and stay committed to working with the underserved!!
