My school was rural and that is way more advanced than mine was.

8: Algebra I 9: Algebra II 10: Geometry 11: Trigonometry 12: Pre-calculus

Advanced class was -1 year. This was Upstate New York 90s/00s. Though I guess to be more specific these courses were actually combination. So it was 3 years of mixed algebra/geometry/trigonometry. Math A, B I think New York called it. Until Pre-calculus Which was actually year and a half courses of mixed topics.

I should've added that I was on the advanced track and was a year ahead of most of my peers, though we had full class of > 20 students (in a graduating class of, I wanna say, ~100-ish) who were in this track. IIRC, it was a toss up what most students did for Math in the 11th and 12th grade. I do believe that the school offered a dedicated Trigonometry and Pre-Calculus course that many students took in the 11th and 12th grades, and there was also an Algebra-based Physics class that students could take, but I want to say that they were not necessary for graduation.
