I am the Msc in Economic student now. Don't say anything without evidence. Last year the reason for some Chinese who did not get their degree is that they use direct quotation but not mark that. We call that 'plagiarism' here. As to the course, they are really ##被过滤##ing difficult. That's undoubtful true. I do not advise you come here unless you have very very strong enthusiam in economics. Try to read Econometric analysis written by William Greene. That's a good way to evaluate whether you are fit or not.
