Mathematics:

You can try to reason about the theorems in the textbook. This will not only improve your proof ability, but also deepen your understanding of formulas. There are also a lot of practice questions. Basically, after each class, you will have to do extracurricular exercises (excluding the teacher's homework). The improvement of mathematics scores and the mastery of mathematics methods are inseparable from the good study habits of students. Therefore. Good mathematics study habits include: listening, reading, exploring, and doing homework. Listening: You should grasp the main contradictions and problems in the lecture, think in sync with the teacher's explanation as much as possible when listening, and take notes when necessary.

After a period of study, you should organize your thoughts to form your own the rules of thinking. Homework: Review first and then do homework. Think first before writing. Do one type of questions to understand a large area. Do homework carefully and write in a standardized way. Only in this way can you learn mathematics well by being down-to-earth and taking one step at a time. In short, in the process of learning mathematics, we must realize the importance of mathematics, give full play to our subjective initiative, pay attention to small details, develop good mathematics learning habits, and then cultivate the ability to think, analyze and solve problems. , finally learn mathematics well.

In short, it is a process of accumulation. The more you know, the better you learn, so remember more and choose your own method. I wish you success in your studies!
