Math 2 for postgraduate entrance examination is deeper than Math 3. Although Math II takes a course of "Probability Theory and Mathematical Statistics" more than Math III, it is obviously much more difficult for Math II to have higher numbers and linear algebra than Math III. The scope of Math III is the same as Math II, including high numbers, linear algebra and probability theory, but Math III is only superficial learning, and its difficulty is not even as good as Math II.

According to the different requirements of various disciplines and majors on the mathematical knowledge and ability that graduate students should have when entering the postgraduate entrance examination, there are three kinds of postgraduate entrance examination papers: one is engineering, the other is mathematics; Mathematics III is aimed at economic management. As for which majors need to take Math I, Math II or Math III, you can refer to Baidu Encyclopedia:
