The second is to ask questions. After last night, you must correct your mistakes. If you are wrong, you must ask the teacher. The more mistakes you make, the more you have to find them.
The third is to sum up the wrong questions, sum up your own wrong questions and find out the principle.
If you persist in the third year of high school, you will win, and doing problems will enrich your life.
Just combine work and rest, remember that there is no once-and-for-all method, and persistence will always have an effect ~
