In my personal experience, the focus of learning mathematics is sorting and classification. Math problems, especially big ones, have limited types of questions. As you are about to enter the third year of senior high school, I suggest that you follow the teacher's review ideas in the last semester of senior high school, and usually pay attention to summing up all kinds of questions in the topics assigned by the teacher, and write down each kind of questions in your notebook. In the next semester of senior three, you need to study the college entrance examination papers for nearly five years and summarize the topics in a similar way. You will find that your carefully organized notebook will become your magic weapon!

You can only review your notebooks before each exam, review your notes one month before the college entrance examination and do a lot of exercises half a month before the college entrance examination. I believe that the results of the college entrance examination will definitely satisfy you! I hope it helps you!

In short, if you want to learn math well, the key is interest, diligence and being good at summing up! Set yourself a goal every day, arrange what you want to review every day, and make up slowly through reference books. The key is to persist!
