Mathematics major is quite special, the postgraduate entrance examination is generally high, and there are few materials that can be reviewed simultaneously. A more comprehensive one is Li Yang's Gao Daidai, which is divided into two versions, the basic version and the enhanced version. The basic edition is to explain the senior generation of East China Normal University and Peking University from beginning to end, including the concepts and examples in the book, especially the exercises after class. Strengthening is to sort out and classify the classic topics and other high-generation materials of major schools in the market over the years, and explain them according to the knowledge points from easy to difficult (all the above contents are used with videos and books). On the whole, the effect is good.
