A learning path is a set of lessons or content items (courses, quizzes, and other materials) that are combined together in one compound course. The path consists of chapters which in turn include courses. 

You can specify if the order of chapters is strict or flexible, set the completion date and the completion condition for chapters and courses, add a certificate that will be issued to the user after they pass the learning path, make it available for purchase, and add it to the catalog.
