2. Mathematics. Mainly by practice. Practice is also about methods. If you are familiar with the same type of questions, there is no need to continue practicing. Do several different types of questions every day, pay attention to the appropriate choice of difficulty, suit your own difficulty, and span as much as possible. It can't all be the same difficulty.

After doing a few things, think about the basic concepts and formulas and combine them.

Finally, it is not that you are stupid, but that you are not sensitive to Chinese and mathematics, which leads to a lack of initiative in learning. It doesn't matter. As long as the teacher praises you more, you will have great enthusiasm. Of course, the teacher will praise you only if you work hard.
