I feel that I want to learn math well, just want to get a high score. Then first of all, you should analyze the types of questions in your exam, such as choice, fill in the blanks and big questions. But no matter what you take, the first three questions of each item (choosing, filling in the blanks and asking big questions are generally the first two) must be the simplest questions, which are basically the basis of the exam, so you must not lose points on these questions during the exam, which depends on your careful listening in class. Generally speaking, you should practice these questions quickly and accurately. In the real exam, you must not waste your time on these problems, because some of the latter problems will take half an hour to solve. Then there is the question in the middle of each project. To tell the truth, is it difficult to say these questions? These questions are basically based on those simple questions. This requires you to work harder in your usual study. It's no use practicing math in high school. It is said that your thinking is still unclear. How many methods have you practiced? Do you do it or not? Therefore, when the teacher talks about examples, exercises or papers in class, you should be serious. Take notes carefully. After class, you don't just listen. You should look at the questions you have done, the notes you have made, the organization you have organized, sort out the teacher's thoughts, and understand why you are doing this every step. You can't guarantee that you can do every problem well, but you must ensure that you know how to do the problems you have read. Basically, when you ensure that you can get points for both simple and medium questions, you will have no problem passing. Finally, there is a difficult problem. Seriously, at that time, the papers we practiced before the college entrance examination, and sometimes the last fill-in-the-blank question we chose was quite abnormal. Sometimes when several teachers study a problem, we usually choose to give up (when I say exam), because solving these problems requires your usual accumulation. There is no way to solve them, but the last question of the big question must be answered, because this question is generally divided into three or four questions, but only the last one or two.
Hehe, after all that talk, you are only a freshman. Even if you start studying now, it's no problem. If you can answer the questions and study math as I said, it will be no problem until the college entrance examination is generally 120 and 130 (full mark: 150).
Don't buy too many reference books, because reference books with different topics may have different answers. If it is too messy, you are just a freshman. You can generally buy problem sets and problem sets. Generally speaking, it is better to choose a big publishing house that is the same as your textbook publishing house, depending on your own situation.
Finally, I hope you have a good trip and get good grades in your studies.
