@aspiringgirl, definitely find out as much as you can about what exactly you would be doing in this particular program that it takes up a lot of your school day to where you’d be forced to take classes in the summer (which I’m assuming wouldn’t be AP level and might thus drop your GPA with the regular GPA), but I also feel like that the AP route is better, esp. with AP US History and taking the exam later and getting credit.
Bachelor/MD program apps are evaluated on a holistic basis with all those areas contributing although probably at different degrees depending on the program: GPA, class rank, standardized test scores, school extracurriculars, medical volunteering/shadowing experiences, community service, plus or minus research. So no one factor will be a shoe-in.
