First of all, before taking math class, we should do necessary preparation, mainly to have a general understanding of the main contents of learning, read the examples in the textbook first, and then continue to do exercises after understanding them. If you don't understand or understand, you can mark it with a pencil in class until the teacher understands. Important formulas must be memorized.

Two minutes before class, you can look at what you previewed yesterday, review formulas and strengthen your memory.

You should always take notes in class, especially the topics you didn't understand yesterday. You should pay more attention to the lectures and record methods. If you really can't remember your notes, you can make a mark first and ask the teacher after class. Sometimes, what you don't understand in the back and the front can be solved in the back. Note-taking should focus on key points, such as the teacher's blackboard writing, problem-solving process and so on.

The homework left by the teacher after class can generally consolidate the knowledge learned in class, so we should pay attention to it. Review the textbooks first and tidy up your notes to avoid mistakes in your homework. After the homework is finished, you can check it with the reference answers at the back. Remember not to correct the mistakes found in the answers when doing the questions. You can prepare a wrong question book separately and record the wrong questions. You can review the above in the final exam.

The above is my experience, I hope I can help you and hope to adopt it.
