As you said, Hohai University's sociology of immigration is the top in China. It seems that there are not many students in this subject, so few people can answer your questions. I suggest you go to some forums of Hohai University to ask questions, such as Hefeng Haiyun or Hehai students in Xici, or send an email directly to the teachers of the school to ask questions. I come from He Hai, but I don't know sociology. Let me answer the general situation of Jiang Hai. 1, the course will not be tense, you should only study for a while, and then you will do some projects and send papers. Be nervous when doing projects and sending papers. 2, basically will not float. When I first entered school, I was divided into first-class and second-class according to my grades, and the first-class ratio was even larger, about 8,000 yuan. In the second year, the study began to be evaluated according to the school performance. If you don't know the subject, there will be a subsidy, which should not be much, and it is not for you to make money. Business trips to buy books or something will be reimbursed. 4. I don't know exactly. The possibility of employment in the education and water conservancy industry should be greater. It seems that the scores of liberal arts postgraduate entrance examination are very high. Good luck!
