I want to be able to make one assessment for multiple classes that would randomly choose questions from a question bank that I provide. For instance, on a specific section of the quiz or test, I want to provide 20 questions, and the system should randomly choose 10 of those questions for each student taking the quiz. That way instead of having to create three or four versions of a quiz to prevent cheating, I could create one, and every student would get a different variation of it.
