80% of the questions in the college entrance examination are basic. I suggest you review every example and connection in the textbook from beginning to end. You'd better do it yourself first, and then compare it with the textbook. Many people think it is useless, on the contrary. If you can write down the steps to solve the problem as an example, then your step score will definitely not be low. Formulas and theorems must be familiar to the heart, and other steps should be written comprehensively. This is a matter that needs to be careful. I believe you will have more confidence in the math of the college entrance examination if you calm down and do it seriously! Come on! I wish you do well in the exam and become the first!
