Certification exams can either be done at any time chosen or right after a training course (which makes you eligible for a discount on the test costs). The IBUQ certifications meet high quality standards. Therefore, exams should be taken at the accredited training centers directly.
Alternativly you can take the exam - without training - directly at the association center in Nuremberg, Germany. The results of online-based exams are announced immediately after the test, those of paper-based tests will be sent vial post.
