@ManaManaWegi, that is really good to know! Remember this situation is my kid has a 730 Math II at the moment. Trying to maximize opportunity for admission to MIT by retaking Math II. Also wondering whether to take a second bite at the apple by taking Math I for the first time to try to get 750 or more (on the same day). Could take both to double chance at a 750+ Math subject test math score (or will this just overwhelm my kid). What is your advice? Kid has strong manifested interest in MIT and engineering (lots of summer STEM programs taken and an internship, though nothing on a recognized national/international level). Just trying to maximize odds.
