Basically, I need students to complete the previous section (e.g. pre-assessment and course flow activity) before they can attempt the next section (e.g. 2 reading materials and 2 quiz). [You will see these "activities" in below image]
All the quizzes are MCQ, and I have set completion tracking for the quizzes in this way:
The problem I met today is, the ticks for quizzes suddenly DISAPPEARED as captured in below image.
It is weird in the sense that the ticks existed yesterday, but disappeared today.
Can anyone help to explain and solve this? Students from now on CANNOT PROCEED ON even they have completed the pre-assessment and course flow activity. In order to help them proceed on, the only thing I can do is to update the grades manually in grader report, which cannot be a long-term solution.
