I happen to be a high school math teacher. Seeing your confusion, let me say a few words!
First of all, we need to cultivate interest.
You can't hate math just because your grades are poor. You can ignore your grades for a while, accept math slowly first, and calm down and study hard. After a period of time, you will find that your grades have improved a little unconsciously, and then you may have a certain sense of accomplishment. At the same time, you will gradually like math.
Secondly, if the foundation is poor, we must first make up the basic knowledge.
If the basic knowledge doesn't pass. It's best to read the knowledge points in the book first, chapter by chapter, or find a reference book that classifies the knowledge of each chapter. It's best not to memorize these knowledge by rote. You should have your own understanding. If you really don't understand, remember it first and digest it slowly later. After reading a chapter, you should do the exercises at the back of the book or the corresponding exercises in the reference book to test the reading effect. Read the next chapter after the exam. ……
The goal of the first round of review should be to pass all the basic knowledge points, and the result of achieving this goal is that the score of 150 should be around 100. Every time you put forward a knowledge point, you can tell the specific content in your own words and solve some problems of directly using the knowledge point.
If you have passed the basic knowledge and want to improve it further, please contact me and I will give you further guidance.
