In addition, GRE is very important for studying abroad (business, GMAT). At the same time, it is best to have IELTS scores, and TOEFL in the United States may be better. However, if you can attach so much importance to English, I think there should be no big problem with TOEFL or IELTS. Neither of these is very difficult. TOEFL IELTS score is valid for two years and GRE score is valid for five years. But some schools require GRE scores in the last three years and IELTS scores in the last year, so you should also pay attention to it ~
In addition: the abbreviation of TOEFL is TOEFL. There seems to be a mistake upstairs.
