Arithmetic, geometry, algebra, statistics, calculus, trigonometric function, generally so many courses, each course has its own teaching materials, I know there are calculus books on Taobao, what published the sixth edition, other estimates are difficult to buy.

If you take the sat, buying a copy of Barron's math is far beyond the scope of the exam.

But if it's ap, it's better to have textbooks to study. Calculus in China is somewhat different from that in the United States.
