If you fail a test then you need to retake the test until you pass. Quizzes are mainly used for practice sessions and are easy to pass after some practice. You can also retake Quiz until you grasp the subject. You can only go to the next training session once you complete your existing session successfully. Your teacher or trainer controls the quality of teaching and training delivery. If your teacher or trainer is not satisfied with your work then he would not allow you to move onto the next chapter. In other words, it is controlled and guided learning and training at the ADMI ensuring high-quality program delivery and outcomes.
