This is also a special major. I majored in cross-examination management. Because when listening to some postgraduate lectures before, the teacher always said that management should not be separated from the family, and mathematics should be tested. Later, one of my classmates wanted to enter the management department, and found that some schools were completely idiots when they took math one. Ask the teacher who took the postgraduate entrance examination in Tiandao to know that management and engineering are related majors. All schools took the Math 3 exam, while some schools took the Math 1 exam, with more emphasis on engineering.
Therefore, students who want to enter the management department must go to the school official website or the research recruitment network to see what they are taking. Math 1 is still much more difficult than Math 3.
