Mathematics is as important as other subjects. In recent years, many students failed in mathematics, and asked why. Some of them do less questions, and some only watch online classes without doing them, so the time allocation is not enough. Some math learning methods are wrong, and they don't summarize or review. What's more, they even bought the wrong materials. They obviously took the second math test but bought the third math in probability theory, and so on.

Mathematics review can be divided into three stages, namely, basic stage, intensive stage and sprint stage. Next, I will introduce the review materials and key points of these three stages. No matter which stage of mathematics review, these specific data series are indispensable: Li Yongle's review book, Tang Jiafeng's review book, Zhang Yu's postgraduate mathematics series, lin li's postgraduate mathematics series and Li Zhengyuan's postgraduate mathematics series.
