Don't be intimidated by numbers. GPAs don't mean anything by themselves, they are just part of a big picture. I would like to tell you my story. I applied late to schools (late december), took the DATs with only 2 weeks of prep, scored a mere 18. My GPA was around 3.1. But YET: I got into all of my top choice schools, which include: NYU, Tufts, Penn, and BU. To my opinion, the most important factor is the way you present yourself during the interview, the self-confidence and genuine enthusiasm you express about the profession, and determination. I can say that all my interviewers loved me and wanted me in their schools. If you know that dentistry is right for you and you can convince your interviewers of that fact, plus demonstrate some maturity, you're in. My essay helped a lot also. I talked a lot about my personal motivations and values. So don't despair even if you have low grades. Remember me!
