Groups of lessons for learner drivers - or where they take place (4-7)

'groups' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'lessons for learner drivers or where they take place' is the wordplay.
I cannot quite understand how this works, but
'lessons' could be 'course' (a course has lessons) and 'course' is found within the answer.
'learner' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is found in the answer.
'take place' could be 'go' (going is a kind of taking place) and 'go' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

'of' acts as a link.

Can you help me to learn more?
