I have a 3.2 GPA (2.85 science GPA). First gen college grad, separated parents, had 2 jobs throughout college (worked full time all summers), volunteered all fours years (and in another country), performed research, honors society, and participated in various other organizations.
The program's competitiveness doesn't focus on statistics alone (because I wasn't sure if I would even get an interview let alone actually getting accepted when I applied). I strongly believe they focus on the person as a whole, using the application questions and the personal statement as a guideline. I also heard they aren't necessarily looking for the best academic candidate in the pool. If you're an honest, sincere, hardworking person and you show that through your application I don't see why you wouldn't be a competitive applicant. I think my personal statement (from AMCAS) helped me stand out on the application.
When I interviewed, the first thing I noticed from the other candidates was that a majority had their Masters degree, medical assistant certification, was a part of a research lab, etc (one was even a pharmacist). Everybody was very active in some way relating to medicine. Hope this helps!
