It depends on the major. I graduated from a western university. At that time, a college had several majors, some of which were allowed to take postgraduate entrance examinations, while others were not. It mainly depends on whether there are any brother colleges in your major. How can I put it? Some schools or colleges are brother colleges, so they will recommend better students to each other, which gradually forms the postgraduate entrance examination. Politics is considered as the most informative course. I think online courses in politics are enough. There is no need to attend the whole course, which is quite a waste of money. At that time, I mainly used the online course of Tiandao Postgraduate Entrance Examination Politics to learn the way and language of answering questions, and I didn't know how to write the real exam. Do more multiple-choice questions and recite more big political questions.
