Option to re-take quiz twice
I have a course with a quiz at the end. I would like to offer the user two attempts to pass the quiz (100%). After two attempts I would like the Retry Quiz button disabled and I want them to re-take the course. When I preview the course I purposely fail the quiz. It takes me back to the beginning of the quiz, but I cannot choose an answer. What am I doing wrong? Thanks in advance for your help!
