1, the basic knowledge must be passed, and there must be a perfect knowledge system. Mathematical finale synthesis involves many knowledge points. If the knowledge system is not perfect, it is likely to lead to a problem in a small link and the whole problem will not be answered. In order to answer these questions quickly and accurately, the basic work must be solid, learn to closely combine the conditions of the topic with the knowledge points, and analyze the hidden information behind the known conditions, which is often the breakthrough to solve the problem.

2, must be familiar with commonly used mathematical ideas, understand their adaptation conditions, methods and conditions. At the end of the senior high school entrance examination, we usually examine mathematical thinking methods such as the combination of numbers and shapes, classified discussion ideas, equations and algebra ideas, overall ideas and hypothetical ideas. In order to answer the finale quickly and accurately, these ideas and methods are essential, so we must learn and use them more in our usual study and practice.

3, the problem-solving strategy should be clear, find a breakthrough, and every breakthrough, no matter how complicated the topic, has a breakthrough. As long as we find a breakthrough, many problems will be solved. How to find a breakthrough? It is necessary to carefully analyze the conditions of the project, and the use method of each condition is basically fixed. We must pay attention to thinking and summing up in our usual study. The answers to many questions are often procedural and formulaic. If you master the ideas and methods, the questions will be easy to answer.

4, Kung Fu in peacetime, the ideas and methods of solving problems must sum up thinking, the topic will be wireless, but the ideas and methods of solving problems are limited. For example, there are many geometric models in geometry problems. Mastering these models can help us find a breakthrough quickly. For example, the common models are congruent hand-in-hand model, K-shaped model, similar vertical model and half-angle model. , as well as some commonly used auxiliary lines, such as cutting short, doubling the middle line and so on. Mastering these models and methods will definitely make you gain a lot.

5. Study the exam questions and simulation questions in previous years. Basically, there are only a few directions and questions to be investigated every year, and then review and conquer according to the direction of the exam. Remember, it is meaningless to pursue speed blindly and ignore the effect. Learn to sum up and think, and then think more when you finish the topic. What is the method and where is the breakthrough? Where are the difficulties and mistakes? The process of solving problems can be divided into several steps. What is the focus of each step? If these problems are understood, then such problems are basic.
