At the moment, when a learner completes a course and answers their questions. If any of the questions are incorrect, the learner is then required to sit through the whole course and answer all the questions again. Even the correct ones.
The proposed solution is an additional feature be developed to store the correct answers and only present the incorrect answers to be answered again. The benefits would be productivity gains in relation to active learning engagement and not wasting time by having the learner complete the whole course and quiz over again.
