Prerequisites are the requirements students must complete before they are able to enroll in the next course of a higher level.
You can enable the Prerequisites addon in the STM LMS > LMS Settings > Addons section of the WordPress dashboard menu.
After, you need to edit a course and set up prerequisites’ settings of a course in the Course Prerequisites section. There, you can add courses that should be completed before purchasing this course. Also, you can specify the passing rate (%) of a prerequisite course.
If students want to enroll in the course, they will see that it has a prerequisite, so they need to accomplish it first.
