What are lesson prerequisites?
Lesson prerequisites are other lessons within the same course that users have to take before they can take a certain lesson. This is great for ensuring that users who take a course have enough prior knowledge to understand the lessons in it.
You can also try creating course paths. This achieves a similar result on the course level as users are guided through a sequence of courses.
