If you want a good shot at getting in, be active. Active means educate people about AA's. Spread the word, show something that proves your enthusiasm. Your GPA is fine. I am not sure about the Mcat though a GRE over 1050 will be good. I dropped biochem once and took it and passed with a C and still got accepted. You will be fine if you apply EARLY. And be active with the school. Make your self available to the program heads at which ever school you want to go to. And if you think you might have a shot at DO school, then apply there too.
