The settings for “Groups” in the course are only relevant if “Groups” are used in the course.

Recommendation: You can set the “Group mode” for each activity individually. It is better to leave the setting for the entire course at “No groups”.

Forces the “Groups” for each activity. See more info on the Groups page.

Groups can be combined into groupings, e.g. to use only a selection of the existing groups. See more info on the Groups page.
