@Ellemay0 Stanford does accept a lot of STEM students, so that makes it harder as you are competing with stronger applicants, versus say Cornell. Know that you have a good shot at most schools, although for HPS and MIT it might be more of a gamble.
@jakeowl MOP does not guarantee top schools, but MIT takes around 80% of MOPpers, according to an AO. That’s good enough for most people. Also, many MOPpers are Asian males.
