They will also see that the various features that have been disabled are now greyed-out or otherwise not available.
Turning it off
Remember to turn it off once the exam period has finished. Otherwise the feature limitations will continue to apply for all members of the class.
Note: It will turn off automatically after a delay of 3 months, to avoid affecting students during the next academic year if a teacher accidentally leaves exam mode on.
