First: remember the outline. The teacher will write the outline of this lesson on the left side of the blackboard every time he attends class. This is the content of this lesson prepared by the teacher before class. With this, we can know what this lesson is about.

Second: remember the attachment. In class, teachers sometimes add some words that are not in the textbook, which is a summary of knowledge and is often ignored by students. These contents can not only stimulate the development of students' thinking, but also help students improve their basic skills.

Third: take examples. In each class, the teacher will show the students some novel examples, and pass on common problem-solving skills and methods to the students through these examples. Recording these examples and making students familiar with the methods of these examples is an important way to improve their grades.

Fourth: remember the questions. Some students listen to the teacher in class, but they are afraid of affecting everyone's class. They are afraid to ask questions and want to solve problems, but they may forget. Therefore, there are more and more problems accumulated in the end, resulting in no improvement in grades.

Fifth: Remember to summarize. Every time you learn a knowledge, a new knowledge, or a new method to solve a problem, you should record your own experience, then chew it carefully and think: where is the focus of knowledge, where is the new method to solve the problem, and how to use similar problems in the future.
