I need to quickly target my reading so I'm asking for help - I am trying to do my first ever exam in Canvas. I want to have groups of questions (8 groups) and then have canvas choose 1 from each group. I am a bit confused about the groups - will the students choose the question or will canvas choose one for them from each group. My answers will be file upload type answers. And what does Shuffle Answers mean? Does it mean to shuffle the a,b, c, d in a multiple choice question?
