My school district does geometry before A2, and it seems the other school districts around here do likewise. There's a state standardized test for all three of the courses so I think the sequencing must be pretty much the same statewide here.

Our algebra 2 curriculum required geometry. I was in A2/Trig combined so my specific examples might not be generally true, but even for just A2, it's after geometry. The high school I went to does IB so some of the sequences are a little different.

I did A1 (8), Geo (9), A2/T (10), HL Methods 1 (11), HL Methods 2 (12). HL math methods is kind of like AP calc but we also do 3D vectors, some advanced algebra and trig stuff that's kind of random, probability and statistics, and our option was series and diff eqs. There's also SL methods, which covers a somewhat less material, and IB math studies, which is sort of like AP stat.

My methods teacher was a little...interesting, and I was kind of burned out on math, so I didn't take it last year. Next semester I'll probably take econ stat which I'm sure I'll hate because I've never been a prob/stat person.
