I have a course with a few content screens, then a quiz question, them some more screens, etc. We are not using the left menu nav, and we are using restricted navigation. We are also requiring learners to take the quiz question when they go through the course. If a learner wants to navigate back through the entire course, they hit a quiz question and they have to answer it before going back more. Is there any way to enable the learner to go backward through a quiz question without answering it, but still keeping it mandatory the first time through?
