Engine (under Joomla, Wordpress etc) for online lessons?

Question

CMS

There is such a task - online lessons for students via Skype
I want to do something similar to the lesson schedule.
Those. the client registers on the site, makes an advance payment, receives the status of "student" and gets access to the online lesson schedule, independently choosing the dates and times of the lesson that are convenient for him.
It seems to me that someone is already using this. Please tell me if there are such engines and what they are called.
