When you create a quiz, Quiz Center stores the quiz in your Custom Classroom account, which only you have access to. For students to go online and take the quiz, you must provide them with the web page address where the quiz is located. The quiz must exist before it can be restricted. Set up groups You must set up a group before you can restrict a quiz. When you select Set Up a New Group from the Your Groups menu of Quiz Center, you're taken to a page with blank fields and instructions for setting up a new group.
Passwords can be anything.
Think of something hard to guess, but easy to remember. If you prefer, you can assign individual usernames and passwords to each member of the group. You can either add these members when you initially set up the group, or at a later time through the Your Groups menu of Quiz Center. You can also remove members from the group, view the group and its members, change group passwords, or delete an entire group at once-all through the Your Groups menu. Once you've created the quiz and set up a group, you can now restrict the quiz.
