Postgraduate entrance examination refers to the general name of relevant examinations organized by the education authorities or enrollment institutions for the selection of graduate students, which is composed of unified examinations organized by the national examination authorities and interviews organized by enrollment units. Postgraduate entrance examination is divided into two levels: master's degree and doctor's degree. Due to different levels, regions, disciplines and majors, the selection requirements are also different. The national unified examination subjects generally include foreign languages, politics, specialized courses and comprehensive courses.

Graduate students can also be divided into full-time and on-the-job types. The biggest difference between the two is that full-time graduates have academic qualifications, while on-the-job graduates only have degrees. The initial examination subjects are proposed by the admissions unit. Those who have completed all the required courses and passed the examination and passed the master's thesis defense will be awarded the master's degree graduation certificate and master's degree certificate issued by the state.

There are three forms of learning: full-time, part-time and on-the-job learning.
