Hi there,

Thanks for contacting us. There is no way to specific way to find out the students which has been purchased. You can check order area.

-Thanks

That is, if a student has bought a course, he needs to register on the site, then I need to manually assign him a group of users with access to the purchased course?

Yes, Exactly

And if the course has limited access? For example, for 1 month, then in a month how can I delete students ' access to this course?

There is no way to manage this option. Thanks
