Actually, I'm good at math. You can divide mathematics into several categories and review them in different categories. Divided into two categories: number and geometry. Numbers are divided into real numbers and imaginary numbers, and geometry is to prove and find the area. You can start sorting out from the first grade, copy down the previous wrong questions, write down the reasons for the mistakes and reflect. Then sort out a knowledge point and concept in a book and do the classic topic again. Do new questions and competition questions.
