About going to the United States for a high school math class;
1, the mathematics curriculum in American high schools is simpler than that in our country.
2. American mathematics is generally taught in the order of basic algebra-geometry-advanced algebra-preparatory calculus-calculus.
3. Generally, you can prepare calculus directly after finishing junior high school in China, which mainly involves some functions, especially trigonometric functions. After studying preparatory calculus, theoretically you have finished studying high school mathematics.
4. Then you can take courses such as calculus. Calculus belongs to AP class, which means advanced placement, and refers to the basic course for freshmen open to senior high school students. There are two kinds: AB and BC. The latter has more contents about sequence, convergence judgment and Taylor expansion than the former.
Ninth grade mathematics (algebra 1)
10 grade mathematics (geometry)
1 1 Grade Mathematics (Algebra 2)
12 grade mathematics (required course of calculus before calculus)
Compared with the level of domestic students, American geometry is too simple. You can take algebra two. If your school offers AP courses, I suggest you study math subjects or take AP Chinese directly, because arts and science are really difficult to learn. There are many first-hand and second-hand tutorials on Amazon. You can choose Kaplan's counseling book. If you start studying now, you will have to wait until next year to take the AP exam.
