Preview before class is very important, which allows us to concentrate the knowledge points that we didn't understand during preview and review them in time after class. After all, it's easy to forget when we listen in class without consolidation.
2. Summarize the wrong question bank
When studying mathematics, we can use our notebooks to record our mistakes and go back and do them again every three days or so. Some wrong questions may have been done at that time, but they may have been forgotten in a few days.
3. Don't care too much about difficult problems
When studying mathematics, we will encounter many kinds of problems. Sometimes, teachers may not be able to solve them. At this time, we don't have to care too much. We will concentrate on understanding and doing basic questions, and most of them are still basic questions during the exam!
Homework is very important.
An important way to learn mathematics is to finish the homework assigned by the teacher. It is not enough to just attend classes. Colleagues who finish the homework assigned by the teacher should do more exercises to consolidate after class.
