Quiz Review shows correct/incorrect but not student's answer
I was going through my project and fixing things. I have four sections of quiz questions. At the end of each section, I have a result page with a "Review" button. I have "Allow user to review quiz" and "show correct/incorrect responses when reviewing" checked.
It was working, until I added some variables on some other slides that are not related to these quiz slides --- after that, student's answers won't show when reviewing quiz. Only the correct answer will show. Plus, it would mark all the answered questions as answered "incorrect" , even the question was answered correctly.
Can anyone help me to get the student answers back?
