Configuring visibility and access
What you need to know
You should only restrict the visibility or access of individual course elements if this makes didactic sense at certain points in your course (e.g., make course content visible/accessible at a later point in time, make course content visible/accessible depending on an assessment).
Basically, the following applies:
(1) visibility always constrains access; and
(2) all elements directly subordinated to this structure element inherit the visibility and/or access rules set on a structure element.
