You are not alone. I was rejected today too, from Comp Sci, with stats similar to yours, from specialized NYC High School. Not even offered AOI or admission as undecided or to another major!
Glad I have a bunch of other good options lined up but this is insane.
It looks like comp sci in-state students got screwed by Stony this year.
Have you considered emailing Stony Brook to see if there was an error? My son, 1530 SAT, 97.75% average from NYC Specialized High School. He was initially rejected from CUNY - City College. He emailed the admission office. They responded within the week that there was a technical error at the Admissions Office and he was admitted shortly after that.
Tech sent over a thousand apps to Stony this years. Stony rejects many qualified students from here because they can’t fill their entire incoming class with a single high school.
