Automatically hide and show sections using restrict access

If you want to hide a section ( eg "Monday" or "Skill Builder") so students can't see it or access  it until a chosen day and time, use "Restrict access".  Go to what you want hidden - the "section". Choose "Edit section". Choose "Restrict access". Choose "Date". From the drop down menus select the date and time (the time  that you want this section to be visible to students from). Add more restrictions if you want to. Finally save your changes. There are a number of items you can restrict access on, but date is the simplest and most common for WBT.
