Since I entered the third grade, my grades have gradually declined, and mathematics has become my shortcoming. I don't know what to do.

Everyone has a weak subject, and everyone has a weak thinking. Normal high school college entrance examination will be divided into arts and sciences, and it will be better in the future. The knowledge feeling of junior high school is a complete set of roads. Therefore, for relatively weak subjects, we should pay attention to basic knowledge, basic questions and medium questions. What is your idea of summarizing the topic? Summarize the routine and you will get a class of questions. Give up difficult knowledge problems. Don't buckle the problem. If you buckle like this, the exam will look different again, but it won't. It's a waste of effort. Study is for scoring, not for arguing. Spend time where you can get points.) Weak subjects can guarantee basic questions, and medium questions can get points. It's normal for my grades to change. I also fell from 19 to 80 in junior high school for three years. With the progress of learning, knowledge is also changing, so it is normal that the ranking is also changing. Don't have too much psychological pressure because of the change of grades. You said the teacher was disappointed. I think there is a misunderstanding or you think too much. As a teacher, he has seen more and taught more students. It is normal for students' grades to change with grades. It is generally believed that teachers also know that you have worked hard and will understand you. Dear, there is nothing to feel inferior about. Just accept yourself and stand on your side. Cheer yourself up. Some students laugh at you. In fact, some students in junior high school just can't play together, so just play by yourself. Some students laugh at you, but in fact he is wrong. He has no quality and doesn't respect others, so leave him alone. Everyone. Some people like it, some people hate it. This has nothing to do with what you did right or wrong. Even if your grades don't drop, he may not like you. Just ignore such people. Therefore, learning is to learn weak subjects as much as possible, and it is enough to grasp the scores of basic questions and medium-difficult questions (summarize the routines for doing questions). ), then. Give full play to your dominant subjects and don't have too much pressure. I believe you can do it. Don't think too much.
