don't they give like grades and rank you or something? Someone brought this up a while ago this year and I thought that is a terrible way of spending your summer in confrontation to research/travel. Unless you are a borderline applicant and you REALLY want to get into that one specific school, I don't think it matters. If anything, there are more chances of it hurting you since if you don't do well, it will show. I know a couple of people who did this type of program 50/50% got into medical school. Don't really know if I care enough to apply.
