Downloads are only for working on your own computer.
Reset releases and completion for all nine lectures into a new private course generation and close the active quiz. Permanently remove all in-class notebook submissions, including every older submitted version.
Keep homework (including legacy homework), student working files, uploaded assignments, resources, releases, delivery records and quiz history. Unclassified legacy submissions are excluded. This cannot undo files already downloaded.
