Users inside a course can have the following status:

Active: it means that the user can access to the course
Pending: in this case the user has been authorized for the course, but has first to complete some steps (either some pre-requisite courses, or a pre-test to assess the initial knowledge of the user) before automatically obtaining the access to the course.
Blocked : in this case the user cannot access the course

The same status can be defined at class level. In this case the status will be transmitted to the user inside each course composing the class.
