GRE, the full name of Graduate Record Examination, is called American Graduate Entrance Examination in Chinese, which is applicable to all majors except law and business, and sponsored by educational testing service (ETS). GRE is an examination result required by all kinds of graduate schools in universities all over the world (except management schools and law schools), and it is also the most important criterion for professors to award scholarships to applicants.
GRE was first jointly organized by Harvard, Yale, Columbia and Princeton University in the United States. It was originally undertaken by Carnegie Foundation and handed over from 1948 to the newly established education examination center ETS. Since then, it has been held in many parts of the world every year.
China Foreign Examination Coordination Office is responsible for the centralized management and undertaking of foreign examinations such as GRE in China. Some famous American universities regard GRE scores as "recommended scores": I hope that applicants can provide this score, regardless of whether their undergraduate majors are the same as their own graduate majors, but this is not a necessary condition.
At this time, if you can provide special GRE scores, it is very beneficial to apply for scholarships. Therefore, if the applicant has enough time, he might as well take a special exam. An excellent GRE score can reflect the applicant's professional quality and learning potential. The GRE general exam is a necessary exam for applying for postgraduate entrance, and LSAT or GMAT is used to replace the GRE general exam for applying for graduate students in law or business.
Now American universities don't have as high a demand for the sense of substitution of grades as before. Many schools can provide any scores of GRE or GMAT as the scores that business graduate students should provide, and law graduate students also use GRE scores instead of LSAT scores.
