GRE (Postgraduate Entrance Examination) is a postgraduate entrance examination, which is suitable for postgraduate students in various disciplines and majors except LSAT and GMAT. There are two kinds of GRE exams. One is the GRE general exam, which is taken by most students in China. The other is GRE. There are not many candidates taking GRE courses in China, because most American colleges and universities do not require special GRE scores, but only ordinary GRE scores. However, applicants who apply for a postgraduate major that is inconsistent with the applicant's undergraduate major need to provide special GRE scores. For example, Mr. A has obtained a bachelor's degree in physics from a domestic university, and wants to go to the United States to study for a master's degree in economics. He needs to provide the GRE test results in economics. If he wants to study for a master's degree in biochemistry, he needs to provide GRE biochemistry scores. If the undergraduate major is the same as the postgraduate major, there is generally no need to provide special grades.

In China, the GRE professional examinations provided by ETS are divided into mathematics, biology, physics, chemistry, history, music, French, Spanish, computer, economics, engineering, education, geology, English literature, politics, psychology and sociology, and the number and form of questions in each subject are different. Its main purpose is to test candidates' knowledge, skills and abilities in a certain discipline or professional field. (After April 2000, the special examinations of history and sociology were cancelled. )
