Courses are not linked, they are stand-alone. This does not allow an institute/workplace to stop users starting courses that they have not successfully completed prerequisite courses which are essential to have completed before starting the next level.

Describe the solution you'd like
Block a Course being available for a student to start unless they have completed other specified Courses.

Describe alternatives you've considered
None

Additional context
