Maya Lowell High School“went from a 1280 to a 1500 in nine weeks. the predicted range was dead on both times i took the real thing, which is the part i still can’t get over.”
Nina Bergen County Academies“i love the question bank!! its so easy to just do ten and go.”
Marcus Booker T. Washington High School“i started at a 1040 and figured reading was just something you were either good at or you weren’t. Run It Back kept feeding me the exact questions i missed until transitions stopped being my weakest skill. finished at 1290. only thing i’d change is i wish the vocab decks had audio.”
Grace Seoul International School“taking the SAT abroad is stressful enough. the diagnostic told me exactly where i stood on day one so i wasn’t just guessing anymore.”
Chris Cherry Creek High School“spaced review kept bringing back the exact skills i was about to forget. sneaky effective. +230 since october!!”
