@ucbalumnus people often get a “back in my day” warped view of this stuff.
I went to HS in NYC in the 80s and the state didn’t require any HS math AT ALL. None. The state reqs back then were very few, at least for independent schools. 4 years English, 1 year US History. I think that was it.
Current NYS state students have a pretty rigorous set of requirements.
