My science GPA is only a 3.0, overall is 3.2, MCAT 33, and I've been accepted at both DO and MD schools. Granted, I have stellar extra curriculars and a graduate degree (MPH). I believe my positive grade trend is what has saved my GPA - I screwed around for the first two years and then did really well my second two years when I took the upper level science courses. I also did really well in grad school.
If you're really committed to medicine, it's never too late to improve your application.
thank you, sir for giving me hope.
