BuddyPress.org

What is the difference between the type of Members vs. Groups.

Let me explain my context:

I have two LearnDash courses(CourseA and CourseB), I would like to show all enrolled students of each course. Buddypress has the members section where it shows all members (courseA members + courseB members).

For example:

CourseA: I want to show all students enrolled in CourseA.
StudentA
StudentB
StudentC

CourseB: I want to show all students enrolled in CourseB
StudentD
StudentE
StudentC

How can that be done with BuddyPress, do you have any ideas?

Thanks
