There are many online resources. It is difficult for you to find a senior here. We are all on the same side of the postgraduate entrance examination. I suggest you: first, directly find the seniors of the university to post in the school post bar, and you will find it soon; The second is to go to BBS, postgraduate forum and other forums in the school to find; The third is online shopping. This is how we all look for information. I hope I can help you.
