Case Scenario Critical Reader - Authoring - Integration Into Moodle - Restricting Access
Click the correct gear for what you want to edit. Left one is for the whole section and the one to the right of the document is for that specific document.
Clicking on either gear will take you a settings page, one of the sections is "Restrict Access"
Restricting access to the Topic will hide it until from students until the date given.
Restricting access to a document gray it out but it will say when it will become available.
Note: There are also similar settings in the "General" box in the CSCR Documents. This will look like nothing has changed in the Topic view but I figured out that if you actually click on the document it will say "This Case Scenario Builder module is not currently available"
