My kids are enjoying time4learning, but they seem to think they don't have to take the quizzes because if they don't the lesson still gets marked done. Then, when I go in I see that they did XYZ, but I don't see that they skipped a quiz. Usually by the time I figure it out it is a pain to fix. (because not all lessons HAVE quizzes) Is there a way to not mark lessons done until the quiz is taken?
