I've created a course with three lessons. The first and last lessons are theoretical, the second one is a quiz (excel import) were the user have to pass with a pass rate 100%. This three lessons are required in the course but, when I try to do the lessons as user (not admin, of course) I can pass to the third lessons without complete the second lessons with a pass rate of 100%. It is necessary for me to block the access to third lesson and to the next course. Any help?
