This is a place where your instructor has set up quizzes for you to take. The quizzes are usually dated and time stamped. Which means you can only take them during the times the instructors give you. If you try to take it early or late the system won't let you take it.
Something to remember before you take a quiz is to make sure that the pop-up blocker is off on the computer you are using. The library computers usually have the pop-blocker on, so you need to turn it off by going to the browser (IE, Safari, FoxFire...) and clicking on Tools, Pop-Up Blocker and Turn Off Pop-Up Blocker.
It also helps if you take your quizzes in a quiet place where you will not be distracted. I don't advise taking them around children, wives, siblings, parents, husbands or friends visiting. They will always need something the minute you start the quiz. It is a common phenomenon.
