Well, if medical school acceptance is only dependent on MCAT scores, then no, I'm not an underdog. 😛 But it's not. Anyone thinking that having all perfect stats gives you some kind of open admission to medical school can talk to Wiggy about it. She has the best stats of any pre-med I've ever seen, and I've been teaching pre-meds for going on nine years now.
That being said, I'm not sure that I'd consider myself to be an "underdog" either. I'm kind of a bizarre applicant all around: yeah, I have the highest MCAT, but I also have the lowest GPA (zero), and from a school that many people have never heard of before. 😛 I definitely empathize with the people wondering whether they would get secondaries because their GPAs were too low to meet cutoffs. And since technically this is now my fourth time applying to medical school, I do think that I have some grounds to claim that I've faced an uphill battle. Granted, I didn't take my applications seriously enough as a high school or college student, but I am serious now, and the stakes are higher to me. I have more to lose at this point, because I care about going to medical school much more than I did as an adolescent.
