Are you from Jiangnan University? Me too. Maybe I am also in this field. I also plan to take the postgraduate entrance examination, but I haven't prepared yet.

Let me help you test it at Baidu Tianjin University. Ask and wait for your reply.

Also, you can go to relevant post bars, forums and the like, and you will certainly get something.

There has been a reply. A senior who has already passed the exam said that he wanted the third edition, and then he read the second edition, no problem. So you don't have to worry, even if there is a change, it will certainly not be too big, so read the third edition first. It is estimated that there must be the fourth edition at the beginning of next semester, and it is not too late to read it then.
