Moreover, mathematics is an interlocking subject. If one link is unclear, then the following calculation cannot be carried out. So some people are good at math at first, but they don't understand the content of a class. As a result, the grades are getting worse and worse, which is often the case. China people are different. Even if you don't understand a chapter or a section, it won't affect the later study at all. Therefore, many people will joke that they will never learn math again if they bow their heads and pick up a pen in math class and look up.
This is mainly because mathematics is very relevant, so students are required to lay a good foundation when learning mathematics. If you don't learn basic mathematics well, it will become more and more difficult to learn mathematics, more and more problems you can't learn, and your grades will get worse and worse. Therefore, when learning mathematics, you need to listen carefully in every class. If one link is missing, you probably don't understand how to do the following questions.
So if you learn math in class and find problems or are absent from class, you must find a teacher to make up for them in time. Of course, most people fail in math because they don't have a good grasp of learning methods or are not interested in math at all. Therefore, if you don't want to listen to the teacher, you will miss more and more courses and get worse in math.
