To enroll in your professor's class on PracticePerfect, go to the Videos page and click on the "Join Class" button located at the top of the page. You will need to enter the class code provided by your professor in the text box. Once you click "Join," you will be officially enrolled in the class. Your professor will be able to view your latest quiz scores on video quizzes attempted in graded mode. If you need to drop the class for any reason, you may do so at any time. Upon dropping the class, your professor will no longer have access to your quiz scores. Keep in mind that you can still use PracticePerfect without joining any class.
