In most cases, you cannot retake a final test. Only if the course is included in the curricular programme or if you are enrolled in classes of Dutch as a VDAB student, it is possible to retake a final test.
If a retake is not possible, you can register (and pay) for a follow-up course and take the orientation test of this level. If you pass, you will be allowed to take this level. If not, your registration will be cancelled.← To the FAQ overview
