We moved on from algebra as a focus quickly. In Central Europe, my high school math courses in grades 11 and 12 were about equivalent to math in a CS BSc in uni in the UK. Formal languages, computing, matrices, and other such things. But you could also finish your high school after grade 10 where I was and not learn any advanced math, or simply choose a lower intensity math course.

Regardless, education was rushed in my childhood (90s and 00s) and it was the norm in Europe. I don’t think that was good, it was very stressful and if a kid had to miss school for a few weeks because of a life event, it was very difficult to catch up.
