This is becoming more common. Students are entering high snchool already having taken geometry in the 8th grade. When I graduated in the late 90s, we had calc 3 (we called it multivariable calc) and linear algebra, partially because a bit under half the class would run out of math by their senior year. They also were starting to offer differental equations and complex analysis. This was a magnet program. When I went back for my 20th reunion, I was told only maybe 5-10% didn’t already have geometry.
