1. Understand the basic concepts of high school mathematics: When learning high school mathematics, you must understand the definition and nature of each concept. For example, when learning a function, you should know the definition range, value range and corresponding relationship of the function, and when learning a series, you should know the general term formula and summation formula of the series.

2. Practice basic questions: for each knowledge point, select some typical examples to practice and master the basic methods and steps of solving problems. At the same time, you can test your learning results by doing exercise books or papers.

3. High school mathematics knowledge is extensive and in-depth, which requires students to master the methods and skills of solving problems on the basis of understanding the basic concepts and form their own problem-solving ideas. At the same time, high school mathematics also emphasizes the occurrence, development and practical application of knowledge, requiring students to have certain mathematical thinking and application ability.
