What's the difference between TOEFL, IELTS and SAT?

The difference between the three is that:

International recognition:

IELTS: Suitable for students from European countries, such as Britain, Ireland, New Zealand and Singapore.

TOEFL: Basically, I study in the United States and Canada. Anyone who applies to study in these two countries, whether undergraduate, master or doctor, must have TOEFL scores;

SAT: or its equivalent ACT test scores must be provided when applying to most American universities.

Difficulty:

TOEFL requires more difficulty in listening and speaking than IELTS, and TOEFL has more multiple-choice questions.

IELTS reading is more difficult than TOEFL, and there are many fill-in-the-blank questions.

SAT is divided into reading, grammar and mathematics, and writing is changed to optional test. Pay attention to the ability to learn, practice, analyze and solve problems.

Practicality:

STA: It's good for finding a job in the future. Some foreign companies pay less attention to IELTS and TOEFL at work than STA.

TOEFL: It is best to take TOEFL when going abroad to the United States, which has higher requirements for IELTS;

IELTS: It is highly recognized by Commonwealth countries to take exams abroad, which is simpler than TOEFL.
