I have used a workaround to copy a quiz I make in Canvas in order to modify the quiz for special needs students. I make my original quiz, send it to commons, then pull it back to the same course. Once I have this copy, I edit the name, change the questions and end up with two versions of the same test. Recently, two other teachers and I have noticed that after students take the modified test, if we want to allow them a second attempt, it strangely reverts back to the original test. How and why is this happening? It has happened to all of us.
