You can create random sections in quizzes to distribute a unique set of questions to individual users. Random sections pull questions from a designated pool of questions stored in the question library.
Since you can only access random sections within quizzes, you must create a quiz before you can create its random sections. You can import an infinite number of questions from Question Library into each random section, but you cannot create new questions within random section folders.
Managing random sections (renaming, reordering, deleting) is similar to managing quiz questions except you cannot publish random sections.
