The test can be done in person or on the computer, though not all test centres offer both versions.
There are several English tests that are accepted around the world as proof of English proficiency.
Below is an overview of the four most widely-used tests: the TOEFL, the IELTS, the CAE, and the CPE.
All grades above a C, the lowest passing grade, will earn them a C1 Advanced certificate. It tests knowledge of English at the C2 level (equivalent to a score of 8.5-9 on the IELTS and well above the maximum score of the TOEFL).
Test takers can earn a grade of (from lowest to highest) C1, C, B, or A.
