1, there is a favorite math material. You should not only finish the above questions, but also understand them.

2, taking the wrong book, not only summing up the wrong questions, but also summing up those difficult problems and clever problem solving.

Textbooks are still the most basic knowledge. Learning textbooks well is also a necessity for learning mathematics.

4. Mathematics is divided into chapters, which requires intensive training for weak chapters, and the skills of summing up can not be ignored. In the naval battle, I didn't see so many problems in mathematics, didn't do so many problems, didn't have a wide range of knowledge and didn't have many skills. It's not that easy to improve quickly. Don't do the problem blindly. You should have goals, plans and skills.
