According to what you said, first of all, your attitude towards learning is very serious, which shows that you have spent time, and it may still be a lot of time; Secondly, getting worse shows that your grades are changing gradually. Thirdly, because of the gradual deterioration of your grades, you already have a fear in your heart, which further aggravates the deterioration of your grades. This illustrates two problems. First, there must be serious problems with your study method. Your present method is not suitable for you. Second, there is a problem with the mentality. I think you don't want to learn math at all now, but you have to spend too much time on it. This is a vicious circle. The more time you spend, the more love you have, and the worse your grades are. At the end of the day, you will completely give up your interest in mathematics. I can't make specific suggestions, because I don't know your current learning methods, and I can only say some general suggestions: First, you must rebuild your confidence in mathematics, and you must never be afraid of mathematics in your heart. If this problem is not solved, no matter what method, it will not achieve the best effect. Secondly, we should change our understanding of mathematics and seek suitable methods. Finally, I'll give you a suggestion, let your brain relax first, give yourself a feeling of forgetting math, and calm down; Then, start learning math again, make sure that you fully understand the topic (based on a certain mathematical foundation, but also on what you said: good grades in Grade One and Grade Two), and then gradually improve your speed. Independent thinking is the key. Teachers and classmates may not be able to help you, because they may not really know you. Only they can fully understand their own problems and solve them.
