Prevent learners from proceeding without passing a quiz
I currently have a course that is made up of 3 sequential levels. I have it set up using variables to where the student cannot proceed to the next level without going through the previous level all the way. Each level has a quiz at the end of it but the learner doesn't have to pass it in order to get through to the next level. I want to make it to where the learner must have a passing grade on the quiz before he/she can proceed to the next level. If they do not pass the quiz I want them to have to go through the level again. It would be nice if I could have them be sent to the slide that corresponds with whatever question they got wrong but this is optional. I know this would involve using variables but I am trying to figure out the best way to do this. Any ideas??
