If you answer quiz questions while logged in to your admin account, your submitted answers will be saved, and you'll see them whenever you return to that quiz in your admin account. When testing student-facing links, make sure to log out of your admin account in all tabs/windows of your browser, or test in a private/incognito window. If you're logged into your admin account when testing you will see any saved quiz answers that you've already submitted, rather than what a student would see. Students accessing the quizzes through the deep links/embed codes should not see any saved progress when they land on a quiz page.
