Lessons settings

Hi, Is there a way of setting lessons/courses to allow users to look back through completed lessons without having to re-answer all the quiz questions again if they have already completed them? The system seems to know that they have already passed a lesson but when they go back to look over the content of the lesson again they then have to re answer the quiz and the system doesn't seem to remember their previous answers. Is it possible to allow them to re-read the theory slides of a lesson without requiring them to re-answer the quiz questions? We would like the system to remember their answers and then populate the quiz pages with their previous answers if they have already completed the lesson. Thanks.
