I never post this, but I have one acceptance (DO), and two interviews (one DO, one MD) in the next month. I had a 497 mcat and a 3.3 science gpa. My application is really strong in certain areas and obviously weak in some. Your application is about balance. While there might be statistical backing to acceptance by mcat and gpa, if you work hard to make yourself a balanced applicant, you will have zero problems. Don't make getting into Med school a "stressor", and just make sure to fill in areas that you know you're weak before you apply.
