Introduction to postgraduate re-examination:

Postgraduate re-examination is an important part of the postgraduate examination system, that is, the second examination organized by the applicant institution after passing the postgraduate entrance examination (initial examination). Generally, it is also divided into written test and interview. The early re-examination of graduate students was mostly a form, but since 2006, the weight of re-examination has been increased for graduate students, and some enrollment units even increased the weight of re-examination to 50%, requiring candidates to have real talent and higher adaptability.

For the preparation of postgraduate re-examination, many teachers in charge of the Admissions Office said: "There is no need to prepare, because the re-examination mainly examines the knowledge accumulation of candidates." However, according to previous years' experience, adequate preparation is also essential to successfully pass the second interview. Solid professional basic skills and good personal comprehensive quality are the necessary conditions for an interview.
