Restricting Access
A course can be set to display everything to everyone all the time, or it can be very restrictive, displaying certain items at certain times, to certain groups or based on performance in previous tasks.
Course items and sections may be manually hidden using the 'hide' icon when editing is turned on. If Restrict access has been enabled by the administrator then a restricted access section will display in each course activity and resource, allowing you to choose how and when this item will be revealed, and whether to hide it completely or show it greyed out with the conditions for access.
