Political mathematics for English majors is essential if you take the postgraduate entrance examination. In the professional direction, we should pay more attention to the basic knowledge such as freedom, and then use it flexibly. I remember that mathematics was the most difficult subject.
Preliminary exam, politics in the morning, math in the afternoon, English the next day, and professional classes in the afternoon. Different majors are different, so is machinery.
The specialized course is mechanical design+mechanical principle, which is in-depth and needs to be understood in class.
Different schools have different arrangements for re-examination, but they are basically written test+interview.
The written test is a professional basic course, such as physical sensor control engineering, manufacturing technology and vehicle engineering. Just learn it well during college, and then review the real questions. There is not much difference every year.
Different research institutes have different geographical locations and research strengths, and the difficulty of postgraduate entrance examination is also different. Good resources are reserved for big cities, so it is generally difficult for research institutes located in developed cities such as Beijing and Shanghai to take postgraduate entrance examinations. For example, automation major in Beijing, Institute of Physics, Northern Institute of Chemistry, Shanghai Institute of Organic Science, etc. The postgraduate entrance examination is as difficult as Tsinghua Peking University, and the competition has been fierce.
However, in some research institutes in cities in the northeast, northwest or midwest, it is much less difficult to take the postgraduate entrance examination, and sometimes even students are dissatisfied and can only complete the enrollment plan by adjustment.
