Is it possible to allow student to redo quiz questions that are incorrectly answered without redoing the entire quiz again.
Setup the quiz so that "Each attempt builds on the last" being set to "Yes".
By making this change, all questions are displayed. Even the questions answered correctly are displayed and editable. However, there is nothing to indicate that the student has answered correctly nor is there indication which questions were incorrect. This option makes it possible for a student to re-do the incorrect questions and leave the right answers.
For further information on how to setup and configure your Quiz, please refer to the following document from our website.
