Believe in yourself. It is difficult to simply say that the postgraduate entrance examination is good, and the difficulty mainly depends on personal foundation and learning ability. Every year, about three self-taught candidates are admitted to graduate students in key universities. Admission mainly depends on the results of the initial test and re-examination. The key is to get the grades up, otherwise even the graduates of famous schools or students of our school will be brushed. For your reference, I hope it will help you.
