I have a course in DominKnow (Flow) which calls for a test out option... I need to provide learners the opportunity to test out of the course if they achieve a passing score of 100%. If they fail to achieve the passing score, they are directed to the start of the course and will need to complete the knowledge check and achieve an 80% passing score. They can retake the knowledge check as many times as needed until they reach the 80%. Is this use case supported in the tool?
