I have some suggestions for learning math. Don't do too many difficult materials when reviewing, mainly focus on textbook knowledge. Review is roughly divided into two rounds. In the first round, we should first understand the examples in the book and remember the conceptual things. Then, you don't have to do all the exercises. Just make a few of each type. In the second round, I bought several sets of middle school exams in previous years, tried to finish them within the specified time, and made my own quizzes. Do classic urgent questions! ! ! It is estimated that the exam will come soon. ..
