First, the basic context of textbooks should be clearly remembered. For junior high school chapters, in fact, its context is basically the same. In each chapter, you will learn the definition first, that is, tell who you are. Then learn its nature, that is, tell you its characteristics. Finally, learn its judgment or practical application, that is, how to judge whether it is it by its characteristics. Or do some practical problems through its characteristics. This may be a little roundabout. For example, we should get to know Wang Wu, then understand the characteristics of Wang Wu, and we can judge that he is Wang Wu by his characteristics when we meet next time. When you define the context of the textbook, when you do a difficult topic, including two or three knowledge points, when you see the key words of the knowledge points, you will immediately think about its nature and judgment. Discover ideas and improve the possibility of making them.

Second, understand the basic context and be familiar with the framework of knowledge points. It is necessary to start practicing this knowledge point deliberately. Don't leave homework for the teacher just knowing it's homework every day. I don't know why the teacher left these homework, and I don't know which knowledge points in these homework need to be practiced. Knowing this, through the practice of practice questions. I should know what I know. Have I mastered this knowledge point? Because of math problems, if you can do it, your thinking is feasible and you can feel it yourself. Once you find that you can't or haven't mastered it, you must learn it again by yourself, ask the teacher and ask the classmates to understand, and don't fall behind.
