I have created Check your Understanding (CYU) questions (Not Graded) for my course. I am able to answer the questions only once. If I need to retake the CYU questions, either I need to login to the course again or refresh the course.
In Articulate 09, I could see a Review Quiz button to see the questions and my responses. Whereas in Articulate 13, all I could see is a FINISH button.
