Hi Joost Elshoff
Hmm, in your response you are speaking about groups, not cohort.
I’ll check documentation concerning this part but as I remember, groups need to be created in a Course or activity context.
For a single level, I’ll have up to 24 courses. If I take the actual system, that means up to around 300 groups per level, for 4 levels, so around 1000 groups that need to be created.
As this kind of teacher works across courses, I primary thought about site wide cohort, that would have been easier to create (only 20 if I count right).
Thanks for answer, I’ll check deeper this group system and see if it can be created automatically (by API for example).
I'll come back to tell if this solutions suits.
