Once a quiz has been completed you will see right away what questions you got right and wrong. After you click out of the quiz you can return to view your quiz results, but you will not be able to see your quiz questions.
There is two ways of going about to view your quiz results. The fastest way is by clicking the quiz icon on the top right corner of the page.
Another way is by going to a chapter with a quiz that has already been completed. The location where the quiz would be should say something like, "Chapter 1 Quiz - Completed." Simply click on the quiz and it will display the Quiz Results.
