AB version is a different version selected by different regions, and there is no distinction between arts and sciences (only senior three mathematics is divided into arts and sciences).

For example, in Sichuan, the non-curriculum grade, the arts and sciences all use the B version.

Because after the division of arts and sciences, I use A to manage B (I was as good as AB before my junior year of science and technology, but A who can finish math is only one-third of our B ...)

And there is analytic geometry in A, but not in B.
