I think you should aim for a 33+ MCAT. If you have zero clinical experience, I'd suggest you wait another year before you apply (about 1.5 years is average. I think a year should be the minimum. Others will tell you that five months might be enough, so opinions vary on this issue. You could have a chance considering the rest of the application looks to be solid). Even so, you need to get that going as soon as possible. If the hospital isn't working out, also consider nursing homes, local family-planning or low income clinics, VA clinic, hospice, rehab facility, etc. Your research, leadership, teaching, and community service, and shadowing look fine. Why no clinical experience to date?
