It is to know what the teacher will say in this class before the teacher attends class, and then you should simply browse the corresponding chapters. For example, in the chapter on quadratic function, we should open the contents of the book before the teacher gives a lecture. Look at this chapter, mainly talking about "the relationship described by quadratic function, knowing parabola, braking distance, image y of quadratic function = AX2+BX+C, and solving the problem of maximum profit and maximum area with quadratic function, quadratic function and unary quadratic equation". Have a general impression in my heart.

Second, correct listening habits.

Unlike liberal arts knowledge, mathematics and physics can't always relax their attention in class, which is especially important for big problems, because it is very likely that a knowledge point will be missed in class and a big problem will not be solved. You must have a good habit of attending classes. Unless the teacher is completely knowledgeable, especially when the teacher explains the topic, you must have a pen in your hand. You can write down the important points the teacher said, you can count the questions you don't understand again, or you can count them on the draft paper before the teacher explains them.

Third, the correct learning attitude.

Be sure to like the class from the bottom of your heart, and you can't be rebellious. This is a question of learning attitude and the key to learning classroom knowledge well.

Fourth, consolidate and practice in time.

The purpose of the exercise is to master the knowledge and be able to do all these questions. For the topic of homework after class, we should try our best to speed up. For topics that you are not good at, you should "think-turn over textbooks-think-find teachers and classmates-think again" A lot of scientific knowledge and skills are easy to forget after we have done it. I think we must firmly grasp the knowledge and problem-solving skills, and do the questions well again and again.
