1. The first volume requires the concepts and representations of functions, exponential functions and logarithmic functions. This part is the basis of the later derivation, generally 2-3 small questions.

2. Derivative. This chapter is usually a grand finale, and sometimes there may be some minor problems.

3. Solve the triangle. This chapter generally tests a big question.

4. series. This part is the focus of the college entrance examination. At present, it is generally one big and one small, and the big questions are very flexible now.

5. Statistical analysis of random variables, their distribution and paired data, these two chapters together look at a big problem.

6. Space vector and solid geometry. This chapter corresponds to the big problem of solid geometry, and the existing difficulty is increasing.

7. Conic curve. This chapter will also have a grand finale. Besides, there is at least one small problem.
