In Hong Kong too, though the dividing is a bit different. High school is like the last 3 years of secondary school, and middle school is like the 3 years in primary school and 3 years in secondary school.

We also have vector and matrix on top of calculus in high school if you take the elective course. The compulsory part contains geometry, complex, probability, etc.

If you want, we have some samples. I took module 2. Compulsory Module 1: Calculus + Statistics Module 2: Algebra + Calculus
