1. Solve the triangle. Only sine theorem and cosine theorem are examined here, and sometimes sum-difference angle formula, auxiliary angle formula and vector are combined.

2. series. The question type is relatively fixed, generally seeking common terms and summarizing.

3. Statistical probability. The points frequently tested in this part are independent event probability calculation formula, binomial distribution, hypergeometric distribution, conditional probability, classical probability, distribution list expectation, linear regression and independence test. Sometimes the topic is difficult, and there may be decision-making questions. You need to choose the right knowledge points according to the background of the topic and make a decision.

4. Solid geometry. The examination method is basically fixed, the first question is parallel and vertical, and the second question is the calculation of spatial angle except the volume and distance of liberal arts mathematics examination.

5. Conic curve. The first conic equation is difficult to solve, and the second Vieta theorem is difficult to deal with.

6. Derivative. The grand finale is the most tested, and the topic is very comprehensive, which can generally be transformed into monotonicity, extreme value, maximum value and constant. Problems such as the root of equation and the deviation of extreme point are being further processed, and this problem can be divided into as many steps as possible.
