Hello Malin,
I will assume the quiz is now closed. In the Quiz settings, make sure that:
- Under 'Common module settings', 'Availability' is set to 'Show on course page'.
This will allow other students to review their quiz if you have selected ✓'The attempt' under 'After the quiz is closed', under 'Review options' in the Quiz settings.
or
- Under 'Common module settings', 'Availability' is set to 'Show on course page'.
and
- Under 'Resctrict access', a 'Date' and/or a 'User profile' restriction is set that allows the ONE student to access the quiz until Friday, 27 March.
This will prevent other students from accessing and therefore reviewing their quiz.
In either case, the quiz mark for all students will continue to appear in the grade book.
