I'm around the same. 28Q is my best. Overall GPA 3.75, Science GPA: 3.58. Right now, I have about 110 hours. I've been updating schools pretty consistently as I gain more hours and talking about what I learned from each experience. By the time I graduate, I should have around 140 hours. I had 3 letters of recs from professors, 3 from research professors, 2 from physicians (though these were a couple days after I was waitlisted and therefore probably don't count), I volunteer pretty consistently, and I have 3 full years, including 2 summers of research.
At any point, did you send in letters of intent? I have, but MCG just says that they received it, but it won't make a difference in my ranking on the waitlist. I'm just getting worried now that I'm getting closer to graduating and having to retake the MCAT and finding a job for the coming year. Any advice on what to do at this point would be helpful!
