I am trying to build a questionbank with multiplce choice question type in moodle version 3.0.4. However, moodle allows me for duplications of the same question. In other word I am having the same question (with same choices) over and oever again. It seems that Moodle does not protect for duplicated questions. So, how can I reveal the same exact same questions in Moodle
I am using aieken format to import questions.
Thank you for your answer and your contributions in advance.
