1. Pay attention to preview before class. If you have enough preview before class, you can listen to the class in a targeted way, and focus on what you don't understand when previewing, so that you won't fall behind the teacher's ideas and save effort when listening to the class. Pay attention to the habit of previewing, which is necessary and long-term for studying science. I suggest you buy a teaching material analysis synchronous study, study more examples and mistakes, and don't just do problems. Doing a lot of problems without thorough research will make you more and more bored and have no interest at all.

2. Pay attention to the content of the teacher's lecture, that is, concentrate on understanding the basic concepts spoken by the teacher and deeply understand the meaning of each concept. For the example the teacher said, you should quickly sort out your own ideas and compare the teacher's answers to see what is different. If not, it is necessary to quickly judge whether it is right or wrong. If it is wrong, you must find the reason for it. If it is the same, you can better find other methods and summarize other methods to solve this kind of problem. Don't ignore what the teacher said simply.

3. Pay attention to the homework left by the teacher. When doing homework, you must be diligent in thinking, take it seriously, and dig out your own methods to solve problems.

4, a certain amount of exercises, topics should be carefully selected, select some typical topics, in the process of doing, pay attention to multiple solutions to one problem, do not just pursue quantity, do more problems will improve the ability to solve problems, especially often sort out wrong questions, carefully study the loopholes in learning.

5. Pay attention to the summary of science chapters, connect scattered knowledge, and thoroughly understand and master the easily confused knowledge.
