Well he went back and did 2 years of grade repair, so it's not unreasonable to think he may have retaken the 23...
Sorry for the late response. Grade repair is exactly what I did. I was a Business Undergrad. My guess is my MCAT was probably among the lowest in the class. I got in with my 23, but I kind of had a rockstar app in everything else. My letter of recommendation was glowing (and you really cant plan it that way, you just have to hope the Doc is cool.) I'm also a combat vet and I wrote about that. I also got nothing but As and Bs at Comm College (which isnt that hard) but I had to take my Orgo's at a big University and my B's were a gift from God there.
Another thing to think about--> I truly am a 2nd yr student right now, so I'm studying for Boards. Buuut, its freaking tough. Remember, when you take Boards, your score is not out of a certain amount, ie. 600/800. Rather, you are compared to everyone who took it and assigned a forced distribution score. So, if you are stupider than everyone else, guess where we end up? That goes in to what kind of Doc you get to become. Just something to think about, particularly when you pay off your 1/4 million dollars in debt. And remember, if you are busting your ass now next to people who arent, once you get into med school, they start busting their ass, and you kind of fall behind.
