While a few high schools across the country (Bard College High School in NYC among them) grant a college associate degree in high school, HYPSM will not accept college credits earned in high school UNLESS those credits are earned at the specific college a student is matriculating to. For example, Harvard WILL accept Harvard summer course credits taken by a high school student on Harvard’s campus, but they will NOT accept summer course credit taken from Yale, Stanford, Princeton or any other college. In addition, they won’t accept any college credits taken during your academic time in high school. Harvard used to address this issue on their website, but I can’t find it, so here’s this from Yale: https://admissions.yale.edu/faq/transfer-program
