Compared with junior high school, the knowledge of senior high school obviously spans one grade and will not adapt at first. When you review the third year of high school in the future, you will know that all the knowledge of high school mathematics is only six. Now, when you are in math class, you should listen to the teacher carefully. Don't be busy taking notes when the teacher is writing on the blackboard. You must understand (I don't have a math notebook yet). Making up notes after class is also a conceptual review. When you encounter ambiguity in class, you must read a book to find out the answer. If you are not sure, you can discuss it with the students with good grades in the class, or simply ask the teacher. Once you think of the knowledge points discussed, it is always difficult to forget them. There is also the need to do a lot of exercises in learning mathematics. You can buy one or two suitable reference books and do more exercises. Finally, the most important point is interest. If only we could cultivate their interest in mathematics. However, this itself cannot be forced. If you want to study liberal arts in the future, it is difficult to be interested in mathematics. Just like when I was in high school, I liked math very much, but I felt general about physics, chemistry and biology, and I was afraid of English! So I spent a lot of spare time counting the learning question bank. I may be a little confused, but I will study hard anyway.
