I have given 2 exams using new quizzes. Both times I have selected a closed date for the test. I allow students to see feedback and incorrect/correct answers with rationale immediately following the exam. I was under the impression that once the test date/time expired this feature was no longer allowed. On both test I have students able to reenter the test, days after it's closed and take screen shots of test questions and answers/feedback. How is this possible?? How is the integrity of the test maintained? How is everyone else adjusting settings in new quizzes to allow results review but prevent the student from reentering and viewing results in the future?
