I was told by one of my interviewers that my score is indicative of success in medical school (28 MCAT: 9P,9B,10V), and I am currently on the waitlist for the second time. Based on this, I would suggest maybe looking into other parts of your applications too (e.g. personal essay, extracurriculars, etc). I do have around a 3.9 GPA, so that is undoubtedly helping me, but I know those before me who have been accepted with 29s and probably lower GPAs. All this being said, I am currently studying again for the MCAT in the event I have to retake it as well as preparing to start a Master's program at Tulane so that I am not being idle for another year. Persistence pays off, so don't give up and keep pushing on!
