Ninth grade introduced me to algebra and my 'technical' high school program spent a lot of resources teaching calculus and algebra. I also opted into all the other math courses they had, doing discrete math, complex numbers and stochastic math. I didn't have points to put into taking it but the school also offered a course on modern physics, teaching stuff like field equations and quantum mysteries. One of my adolescence girlfriends left Russia after fifth grade and had an introduction to both algebra and some discrete math there.
