A Quiz is a type of Exercise that is completed on the Quiz page.
Refer to the Creating Exercises section of the Getting Started tutorial for more details on creating Quiz Exercises.
Quizzes are designed to be done individually in a single sitting. Progress is saved every time an answer is submitted. Navigating between questions is only available if the professor has enabled Backtracking. If Backtracking is disabled, then questions must be answered in the order they appear. Skipping a question will submit an empty answer for the question, and leaving the Quiz page will submit the exercise.
If the Quiz has a time limit, that time limit will start when first starting the exercise, and the timer will continue counting even if not on the Quiz page. The Quiz will be automatically submitted when the timer runs out.
