You can’t start your quiz.

First, make sure that you have disabled any pop-up blockers for your browser, including those included in the popular search toolbars such as Google.

Second, quizzes are typically set up with specific date and time parameters by your instructor. If you cannot see the quiz title in your course, or if you can see the quiz listed, but can’t click on it to start, then please contact your instructor. He or she may need to change a setting on the quiz to make it visible during the scheduled time.
