First of all, read the book, read the outline and summarize the knowledge points. No matter how the topic changes, still talk about knowledge points. Even if the Monkey King can become 72, he is still a monkey, and the reason is the same. You don't have to memorize, but you must understand the meaning and subtext. Understanding it is more effective than watching it a hundred times.

Second, after reading the book, start to do the problem. This time is the time to test your grades, just like looking in a magic mirror. Give it a try and you'll know if you have mastered it. It doesn't have to depend on what you know, but try to understand what you don't know.

Finally, if you know almost everything, don't read any more. Reading before the exam actually doesn't have much effect. You can't eat a fat man in one bite, you will or you won't. It's a movie. Go through the knowledge points in your mind before the exam, and if not, turn over the books again.

Please keep asking questions.
