I attended a decent high school on the U.S. in the late 1980s.

IIRC, I took 5 math courses high school: algebra, geometry, precalc, calc 1, and calc 2.

I don't think we ever covered matrices, except as a condensed format for solving systems of linear equations.

Mine was slightly different with geometry (middle school) > algebra (high school) > trig > calc 1 > calc 2, then in college they had calc 3 (which in hindsight was linear algebra with a heavy physics lean), then differential equations. That was all of my required math, I took two stats courses and a quantitative analysis and a game theory course as electives that all where under math but not required and didn't seem to be in any real order after prereqs.

I graduated in 2021, and my experience corroborates yours. I took that same sequence of math courses, up to calculus 2. If I had been on the more advanced path for math, there was exactly one more class; I don't remember what it was, but it wasn't linear algebra. I only took linear algebra in college.
