First, step by step, don't think about the second interview first, based on the initial test, and then consider the second interview after passing the qualification line, all of which have countermeasures.
Second, the postgraduate entrance examination is your own business, and you hardly need help from others. It's better to have friends, not to be a burden. What information can be found in the postgraduate entrance examination? There are many on the BBS of Tiandi Agricultural University, which can be downloaded.
Third, there are too many books, bookstores and online stores. As for the tutor, you didn't even take the exam. What can I talk about when I contact others? People can't give you any promises. Don't exaggerate the role of the tutor. Achievement is above everything else. The second interview is composed of several tutors, and the role of one teacher is very limited.
The most important thing: keep the right attitude. Postgraduate entrance examination is a selective examination, which is very serious.
For other matters, please refer to BBS of Tiandi Agricultural University of China Agricultural University, "Guidance and Solution to Misunderstandings in Postgraduate Entrance Examination".
