If you choose to duplicate an existing quiz on your GauchoSpace course page, the quiz will be duplicated along with the questions within the quiz. The questions in the duplicated quiz will reference the question bank category used in the original quiz. If questions in the duplicated quiz are changed, then the same questions will also be changed in the original quiz because they are both tied to the same question bank category.
Because the question bank categories are linked, we do not recommend duplicating quizzes. If you do choose to duplicate a quiz then you should delete the questions in the duplicate quiz (this will not delete them from the original quiz) and create or add questions from another question bank category.
