Hi everybody. This is my first post. Thanks for reading. I am almost 23, graduating undergrad after one more semester with a Political Science degree. It will have taken me 5 1/2 years to graduate college. I started out pre-med and bombed it. So, after two years, I changed my major (why it has taken me so long). My overall GPA when I graduate will be about a 3.2. When I was pre-med, I had a really low GPA (around 2.0). But, I have only taken one biology, two chemistry. So, I have a really high grade trend. I am going into the Air Force as an officer with hopes of a 4-5 year tenure there. My question is this: If I re-take the science classes I already have taken and take the additional pre-reqs for med school while in the USAF and do really well on them, then take the MCAT and get a good score, do I have a shot at med school? Or did I pretty much screw my entire life with some mistakes I made when I was 18-20? I was immature back then, but I like to think I have changed dramatically in the last three years, and will even get better while in the Air Force. I'm wondering if I can make up for those mistakes in the eyes of the admissions people. I'm from Georgia, so Georgia Health Sciences University or Emory or Vanderbilt would be ideal. Thanks everybody!
