The ability to reattempt incorrectly answered questions only is limited to tests in the 'Assessment Player' tool.
Unfortunately, this cannot be done with micro quizzes using the 'Course Player' tool.
It is possible to add Feedback per question though, if that is any help? This can be done by:
1. Opening the relevant test
2. Editing the 'Pass / Fail and Resit Settings' (See screenshot attached) and selecting the relevant Feedback Option then saving any changes
3. Editing the relevant questions and selecting the relevant Feedback Option (See screenshot attached), entering the feedback into the available fields and saving any changes
This should update the feedback for the micro quiz and provide the learner some guidance for future attempts.
