I have a large class that is divided into 3 sections (1, 2 and 3) I have added subsequent sections A, B, and C to each section. I would like a way to filter by section and letter group, but I don't see a way to do that. I think it may be that I don't fully understand the cohort/groups/groupings hierarchy. I would also like the grade book to be able to sort this as well, since different markers mark different letter groups within each section.
Can anyone help me out or point me to a source that explains things in term that are applicable to what I'm trying to do?
