Groupings FAQ
From MoodleDocs
What is a grouping?
A grouping is a collection of groups. One group may be present in multiple groupings or no grouping. Groupings were designed to allow selection of different sets of groups in each activity.
What is the difference between a group and a grouping?
Why does a graded activity assigned to a particular grouping only appear in the gradebook for all users?
The gradebook does not currently consider the experimental Available for group members only functionality. (See MDL-13868 for details.) It is recommended that separate courses are used instead.
