First of all, listen to the teacher carefully. Listen attentively, follow the teacher's thinking, don't be distracted, and don't listen at the same time. Secondly, we should pay attention to every word the teacher says, because mathematics is famous for its rigor, and there are serious differences between words, and there are infinite mysteries hidden between words. Pay attention to taking notes when listening to the lecture. Raise your hand to speak actively in class. The benefits of raising your hand are really many! (1) can consolidate the knowledge learned in class. (2) Exercise your eloquence. Those vague ideas and mistakes can be taught by teachers. It's killing three birds with one stone. In short, listening should be done with hands, mouth, eyes, ears and heart.

Second, extracurricular exercises. Confucius said, "Learn from time to time". Homework after class is also an important part of learning and consolidating mathematics. Pay attention to the accuracy and speed of solving problems. Accuracy means accuracy, concentrate on completing your homework independently, strive to be accurate once, and correct any mistakes in time. And speed is to exercise your concentration and sense of urgency.

Third, review and preview. Math review.

Fourth, improve. After reviewing your homework, do some climbing questions. Doing this kind of problem, thinking independently as much as possible and trying to find out the hidden conditions are the key to solving the problem. If you really can't think of it, you need to look at the reference books and consult your teachers and classmates. In short, seeing more, doing more, asking more questions, being open-minded, diligent and keeping a positive spirit are the key.
