Personally, I don't think you are very good at math now. You don't know how to learn math. I think what you need to do now is to do basic math skills, and some basic math concepts and knowledge points must be clear. Then, the mathematics knowledge of grade one is to prepare for grade two and grade three. You can do some questions properly to deepen your understanding and mastery of mathematical concepts, but there is no need to do a lot of questions, so you can only say that you are testing your computing ability, not how deep you know mathematics.

At the same time, junior high school mathematics mainly grasps some basic concepts, such as inequality, sequence, trigonometric function, linear function, quadratic function (principal) and so on. I understand that the list may not be in place. Especially if you learn quadratic function well, it will be much easier in high school. I think the exercises about quadratic function are very simple.

The difficulty of high school mathematics lies in whether you put your heart into it, and there is no problem with your heart. It's not difficult to set a math goal for yourself, and it's not difficult to like her. Many things are interlinked. Personally, I don't think it is necessary to take what the teacher said as the best. I must do it myself, so that I can know why.

When you feel that you are learning well, you can try to do some difficult problems to improve your understanding of mathematics, which is written out. Be sure to do it.

Doing difficult problems-I think it's just a way to satisfy my evaluation of mathematical ability.
