Preview. Doing a good preview is the key. Although it was quite simple at first, it will become more difficult later. Only by previewing well can we learn more efficiently. If you can't learn well in the front, it will be difficult to learn later, because most of the knowledge is related.

Listen carefully in class and take notes. You can write down the questions or problems that you think are enlightening and try to do them again after class, which will help you understand and improve your problem-solving ability. Taking notes will help you review, and you won't fly around like a headless fly.

Review in time. You must review what you have learned in one day. Never put it off until tomorrow. "Tomorrow follows tomorrow. How many tomorrows are there? I will wait for tomorrow. Everything is in vain." If you don't review in time, you will probably forget 60%~75% in one day. I forgot all about it in a few days.

In addition to the above aspects, mathematics should also accumulate a certain amount of questions. I don't advocate sea tactics, but every knowledge point must be pragmatic, and you need to remember besides understanding. The more you learn in high school, the more you will lose if you don't remember. It saves a lot of time to avoid learning after memorizing.

Do a set of wrong questions and have a look every day. Make up all the usual loopholes. ?

Reminder: Do you insist? Take action? Many people will make vows at the end of the day. How about tomorrow? Few people can do it in the end.

In English? Words are the foundation? Without words as the basis, how can we build an English building and hope to adopt it?
