In this video, I explain the exams and how the course editor behaves.
How to make the exam mandatory
You can make an exam mandatory. This means that the exam must be completed. Only after that, your members can start the next lesson. You can activate this simply with the checkmark "mandatory" in the exam lesson.
If you want that your member need to complete the exam before they can start the next section, you need to make the completion of the section mandatory.
Enter the course editor and click on the 3 dot menu. Select edit section>
In this menu, you can make the section mandatory. The "!" next to the section and lecture state button indicates that this section or lecture is mandatory.
