When taking a quiz or test in your Moodle course, it is important to know exactly how much time the student has to attempt the quiz.  Instructors are able to set time limits on quizzes and tests, and the student should most definitely know exactly when the attempts are allowed, not only so they can prepare for the quiz/test, but not miss it entirely and get no credit for taking the quiz/test. In this sample the instructor has laid out a two day time period to take the quiz, and also gives the student just 1 hour and 30 minutes to complete the quiz/test.
