Rule #1: A user may only register for a single instance of a course at any given time. This means that a user can't have multiple admissions to the same course.
Rule #2: Users are only permitted to register themselves for a course. They cannot create admissions for other users.
Rule #3: Once a user upgrades their course admission to a premium level, they will automatically be added to the course squad.
Rule #4: Access to non-free lessons is exclusively provided to users with a premium admission. Users with basic or non-premium admissions will not have access to these lessons.
Rule #5: A user can request a refund until he starts learning.
