1, last semester of senior one: I usually consolidate and review the basic knowledge of mathematics, including the review and expansion of junior high school mathematics. The key learning contents may include algebra foundation, functions and equations, geometry preliminary, etc.

2. Next semester of senior three: further study the core contents of senior high school mathematics, such as functions and images, trigonometric functions, series, mathematical induction, etc. At the same time, it began to involve the application topics and problem-solving skills of high school mathematics.

3. Last semester of Senior Two: The key learning contents may include mathematical analysis, analytic geometry and probability statistics. This stage will further cultivate students' mathematical thinking and problem-solving ability, and pay attention to the connection between mathematics and practical problems.

4. Next semester of senior two: further expand and consolidate all knowledge points of senior high school mathematics, and pay attention to the training of comprehensive application and problem-solving skills. At the same time, I began to review some contents related to the college entrance examination, such as being familiar with math questions and solving methods.

5. Last semester of senior three: mainly systematic review and intensive training of college entrance examination mathematics. Focusing on the test sites, common questions and problem-solving skills of the college entrance examination, simulated exams and real exercises are carried out to improve students' ability to take exams and cope with the college entrance examination.
