If you are interested, you can listen to my method of learning mathematics.
I think if you want to learn math well, you must first understand the teacher's lectures in class and always keep up with the teacher's ideas. If you feel that you can't keep up, you can think more and think more, which will help to improve your thinking. Secondly, it is what the teacher asks to remember, that is, the basic theorems, basic formulas and basic concepts that must be remembered, and recalled in the mind after class or after school. Then, that is, the homework assigned by the teacher must be completed, like those sea tactics, I really don't think it is necessary.
I wonder if it will help you.
