There are two ways to restrict Student access to content on Big Universe, blocking individual books and only allowing books within a specific grade range. You need to be logged in as an Educator plus Admin.
After you have blocked the book, the Read Now button and the book description will no longer be visible; it will be replaced by a restricted content message. You should also see a message that you successfully blocked the book.
To unblock a book, simple click the Unblock button. The book description will reappear and you will get a message that you have successfully removed the book from your blacklist.
Blocking Content by Grade
To only allow books within a set grade range, go to Manage, then select Accounts. Then select your School. Click the Edit School icon. The Grade Range Content Filter will allow you to set the Minimum and Maximum grade levels you would like to allow your users to access. Only an Educator plus Admin user will be able to designate grade levels of books to be blocked from a specific school.
