Students who are not good at mathematics can usually be divided into three situations: the first one is that they have not mastered the methods of learning mathematics because of their poor learning methods. Many students and our one-on-one tutors reported that while studying, although the concepts, formulas and basic problem-solving methods of relevant knowledge were temporarily memorized, they were not applied in time, and the problem-solving methods were not consolidated in time. After a long time, they will find that the content of short-term memory has been forgotten, or the basic questions will not be done if there is a slight change. The second is because the foundation is not good enough. In the process of learning, the mathematical definition and formula memory are not skilled, and the basic problem-solving steps and methods are not well mastered. One-on-one tutors point out that such students think they have almost all this when reading books, but when they encounter exams, they find that they still have a lot of knowledge to master, and they often have trouble doing ambiguous questions. Thirdly, because of the lack of logical thinking ability and habits in mathematics, everyone's thinking ability and habits are different. Some students prefer image and perceptual thinking, while numerical and logical thinking in mathematics are relatively weak. This kind of students will not have much problem with the basic knowledge and understanding of mathematics, but they may find it difficult to deal with some relatively difficult problems. To sum up, the first two situations can actually be improved through effective education. The current teaching requirements in primary and secondary schools are not only set for gifted students, so as long as effective methods are adopted, most students can meet the standards. The third situation varies from person to person and it is difficult to improve in a short time. At present, the questions used to examine students' outstanding ability in the exam are generally controlled within 20%. If students' basic knowledge and understanding reach the standard, it is not difficult to get satisfactory scores. After targeted training, this ability will gradually improve. In view of the above problems, the concrete solutions are given. For students with poor and weak mathematical foundation of the first kind, it is forbidden to make up lessons or do problems blindly. It is suggested that students and parents can choose their own study rules. Nowadays, many students are smart, accept new knowledge quickly and feel good about themselves. But if they don't practice, there will probably be loopholes in the exam in the future. For learning, sometimes you can't fully master it simply by reading books, and you must really master it through practical work. Giving 20 typical questions a week is not a big burden, but it will be of great benefit to help students lay a good foundation. For students who are not good at the second learning method, you can do some exercises. Because most questions will be analyzed by teachers, you can ask teachers or classmates for slightly more difficult questions. If this problem will not or will produce some knowledge problems when doing it, it will be very helpful to understand and deepen the knowledge immediately.
