What's the difference between several English exams? IELTS, TOEFL, BEC, GMAT, SAT and so on. What are generally recognized in China?

TOEFL and IELTS are both language tests, focusing on students' English listening, speaking, reading and writing abilities.

Both TOEIC and BEC are business English, which is more helpful for students looking for a job directly after graduation from college.

GRE and GMAT are graduate entrance examinations in the United States, among which GMAT is mainly aimed at business schools.

Finally, SAT is an entrance examination for high school students when they apply for undergraduate courses.

This is their basic difference, I hope it will help you.
