Applying for American graduate students generally requires two standardized test scores, one is TOEFL or IELTS (one of them), and the other is to submit different test scores according to different professional needs. There are some exceptions, but most of them are necessary.

Gmat: Graduate Management Entrance Examination is an entrance examination for graduate management science. General business projects need to provide this score, especially accounting majors. Only GMAT can be submitted without GRE, and other business majors are allowed to replace GRE. GMAT scores are valid for five years. The examination lasts for three and a half hours, and the main questions include analytical writing (1), comprehensive reasoning (12), quantitative reasoning (37) and textual logical reasoning (4 1). Unlike GRE's rule of scoring according to the correct rate, GMAT scoring is based on the number of questions, whether the answers are correct, the difficulty of the questions and other statistical characteristics of each question. From now on, GMAT has only eight exam opportunities in its life, so students who want to pass multiple exams should pay attention and don't waste exam opportunities at will.

GRE: The Postgraduate Registration Examination is the American Postgraduate Entrance Examination. GRE is applicable to all majors except law and some business subjects. There is no limit to the number of exams, and the results are valid for five years. GRE test is divided into three parts, mathematics, Chinese and writing. Math 130- 170, Chinese 130- 170, writing 0-6. The lowest is 130+ 130+0, and the highest is 170+ 170+6.

In addition to the general test, GRE also has a sub-test called GRE-subject test, which aims to examine candidates' comprehensive professional knowledge and related English ability in a certain subject area. At present, there are eight courses: biochemical cell and molecular biology (biochemistry), English literature (English literature), biology (mathematics), chemistry (chemistry), physics (computer science) and psychology (psychology).

There are three main reasons for taking the Sub exam:

First, the schools and departments that want to apply require GRE scores;

Second, the GPA is not very good, and I want to make up for it by scoring;

Third, interdisciplinary application. However, please pay special attention to whether the subtest matches the major you are applying for.
