I have created the quizzes in an interactive mode that is not implemented because each quiz questions needs 2 hints. I did not know that when I created the quizzes. Each quiz offers feedback for questions if you miss or question or even if you get it right. If you finish your first quiz and want to take it again before submitting it, then notify me and I will delete your first quiz so you can take it again.
Eventually, I will add hints so this is more in the interactive mode. Hang in there. And let me know if you truly want this to change. I can change the quizzes to another mode that does not provide feedback for the answers.
