Like the water supply and drainage major of Southeast University, almost all the information can be found on the websites of the School of Civil Engineering, the Research Admissions Office and the Academic Affairs Office of Southeast University.
Mathematics is nothing more than the best point, and English and politics are the same. It is best to find the real questions of professional courses over the years.
There are five main ways to get the real questions: first, ask the university students and seniors directly; Second, go to the university to find a copy shop in or around the university. General copy shops will keep the previous test papers for future generations to copy. The third is to go to the university to find bookstores and postgraduate agents to buy; Fourth, go to the BBS of the school, the forum for postgraduate study and other forums to find; The fifth is to search and buy on shopping websites such as Taobao. I wish you success:)
