Hi, my name is Peter and I'm trying to find out if its possible to create a quiz on powerpoint that once an incorrect answer has been selected, it can no longer be selected a second time. That is if the choose answer A, and they are directed to a slide that tells them it is wrong, when they return back to the answer list to try again, the previous incorrect answer is no longer an option?
Furthermore, is it possible to have a grading system in powerpoint, where a score based on the amount of correct answers will be added and provide a score at the end?
