Hrrm, good question, I was actually thinking about that earlier for another reason. I think that I personally would try to simply put it under my activities section rather than education- I would consider it more like "on the job training" rather than your run of the mill college education. Still, check into the AAMCS rules, they might require you to list it under education and have your transcripts sent. As long as you did well, I wouldn't hesitate to list it under both since you can't really comment on it in the academic portion. Plus, if they're just skimming your academics there is always the possibility they could miss that important hands-on experience-obtaining endeavor. Out of curiosity, was the program one semester or two?
