We are trying to figure out the least time-consuming way to hide course material from students during exams to mitigate cheating. Ideally, there would be an option for 'teaching staff only' in the course visibility settings. The only option we are coming across is to un-publish course content individually, but that would be tedious for teaching staff to identify the relevant course material. Has anyone else come across this? Are there any other options that I'm missing?
