Hi Lauren, thanks for the insightful reply. My intuition tells me to pick one test, also. It just makes sense to focus your resources into one.
I do have a good grasp on why I want to be an AA (and it is beyond the money.) I have extensive shadowing set up this summer, but haven't been able to figure out how to get relevant patient contact through volunteer work yet.
Anyway, I see your point and appreciate your post. Although I must say that 27 isn't a bad score on the MCAT, and I have to wonder if that didn't speak louder for you than a GRE score would have. Of course it's all speculation. All I can say is I'm envious of you! South is exactly where I want to be. :D
