I have an Ultra course that will be ending at the end of next week, and after I grade all the work, I'll need to prep that course shell for a new set of students. How do I do that efficiently in the new Ultra system? When I delete the students from the roster, is all of their work deleted also (discussions and submitted assignments)? In the previous system, I had to go in and delete all the discussion threads manually, and I would use the select all feature to batch delete their work from a forum. But, the new Ultra system does not have a select all feature that allows instructors to batch delete student discussions. How do I delete student discussion work in Ultra? I certainly hope I don't have to go in and delete each student post individually...
