What is the difference between hiding and restricting activities?
Hiding activities is a quick way to manually control content that course participants see.
Restrict Access is more of an automated way to control access - set a date, designate a group, or use other filters to control the visibility of the content.

It is important to keep in mind:
- Changing the visibility of an activity may result in any corresponding grades to be inaccessible to students. Graded activities will need to be visible for students to see their grades.
- Grade activities that are hidden may impact the total grade for the course.
