Biomedical Summer Program at UPenn

Has anyone ever gone to the biomedical summer program at UPenn? I was wondering if the experience was that great it is pretty expensive. Did you actually learn important topics that helped you as an inspiring Doctor or was it just busy work. Also is it that hard to get into? I have a 96% GPA and have a bunch of extracurricular activities (Vice President of my class, National Honor Society, Red Cross Club, etc). Overall I’m just looking for an overall summary of the biomedical summer program at UPenn.
