I have already created the quizzes for a course, and I need to create copies of them for students who need extra time doing them (the quizzes have a limited time). I wonder if there is a way of copying/duplicating a quiz, and then change its settings (e.g. I can change the time limit, make it available only for one particular student). So far, I haven't found a way to do so, and I had to redo the whole quiz, question by question, as a new quiz.
Any help will be much appreciated!
