Maybe some form of advanced Algebra or Geometry? It probably depends on your state or whatever. Where I'm at, I took Pre-AP Algebra 1 in 8th grade, and now I'm in Pre-AP Geometry in 9th grade. You could choose to take it again, but usually that doesn't do much good.
i think your times tables. A review stuff from grade 3.
Here the order is :
Grade based math until 6th
And after there in my school we had choices between personal finance, statistics, and pre calculus
