You should calm down and read math books and textbooks carefully (don't do other books and questions first). From the first page, read the examples of each section of the book repeatedly and read them all. Grasp the true meaning of all questions. Then do the exercises in the book to check your mastery. If you can't master it well, start reading again Until you really master it. Then you can do some complicated problems.

It's like solving a bunch of messy ropes, you need to solve one buckle at a time, and you need a little real understanding. Only the front knowledge can be learned, and the back knowledge can be learned.

At this time, self-study is very important. As long as you follow this method carefully, all the books should be studied again. Mentality is very important. Don't worry. In this way, you will find that you can learn anything without a teacher, and so can other subjects.

This is a book that has been read a hundred times, and its significance is self-evident! !
