First, remember the key points, difficulties and doubts.

Before each class, the teacher will list the objectives, key points and difficulties of this class, so that we can have a good idea of what to learn in this class. With the goal, it is easier to grasp the key content of this lesson, improve the learning efficiency of the classroom, and write down the key points of this lesson, so that we can easily grasp the core of review in the later review.

Second, remember the conceptual knowledge and conceptual analysis in this section.

Every lesson has new content, and the formation process of each knowledge point concept is also our analytical thinking for solving problems. No matter how the following questions change, the analysis of problem-solving ideas always revolves around these basic concepts, and a thorough understanding of the concepts also lays the foundation for our later problem-solving.

Third, remember the example analysis and problem-solving ideas in this lesson.

After the knowledge content of each class is finished, the teacher will summarize and explain the problems involved in this section. So when we take notes, we should understand the teacher's problem-solving ideas, sort them out by ourselves, write them down, make a comparison with the teacher's process, and then mark them.

Finally, summarize the method of doing this kind of problem and write it in different colors next to this example.

Fourth, remember mistakes and confusion.

After each class, the teacher will assign homework according to the content of this class, write down the problems that are easy to make mistakes in the process of doing it in our notebooks, analyze the reasons for the mistakes, and avoid making the same mistakes next time.
