The national line of postgraduate mathematics varies according to different majors and regions, depending on the specific major to apply for, such as 74 points for managing area A in 2020; 72 points in economics; Science 60, engineering 56. The national line of postgraduate entrance examination is the lowest score that students need to pass. At the same time, there will be scores in all subjects of postgraduate entrance examination. The standard of success in crossing is that all subjects have crossed the national line and the total score has crossed the national line. So how do you look at the single subject score line? For example, the full score of politics and English is 100, which is a single subject (full score = 100), and the full score of mathematics and professional courses is 150.
