You can look at Xue Jinxing's textbooks and Wang Houxiong's suggestions, both of which are good. Choose according to your actual situation. After all, you won't know until you read a book. I have been previewing these two books before, and the effect is good.

However, I have a suggestion. When previewing, you can't just read the book once. When reading, add your own ideas. If you don't understand something, you should read the textbook again. Circle if you don't understand after reading it. Listen carefully to the teacher's analysis in class, and the effect will be good.

In addition, every time you finish reading a chapter, you should draw a picture to summarize it, open the table of contents, and start with the big topic of each chapter, and recall the contents of this chapter section by section, which formulas have appeared, which principles have been stated, and which examples have been cited, so as to strive for your own memory, and if you can't recall it, you should turn over the book and look at it, so as to read the book thinly and see through it, and the future study and review will definitely get twice the result with half the effort.

That's true, but I still practice kung fu by myself. Remember, work hard now and relax later. I believe you understand the truth, because you know how to preview in advance, which shows that you are a smart person. Let's go

Best wishes.
