Multiple-choice questions are often used to assess the user's understanding. However, the system does not know if the user answered randomly, by chance, with confidence or without confidence. The user's confidence can be used as a feedback for teachers or smart interfaces that could understand that he is not sure of himself and then provide further assistance.
