The quiz tool has multiple feedback settings that the course instructor sets for each quiz. After submitting a quiz, you may be able to view your submission (grade and answers) immediately, after a specified time, or not at all. 

To review quiz submissions, navigate to the Quiz tool in D2L by clicking "Assessments" > "Quizzes."

On the list of quizzes, find the desired quiz. Click the actions arrow next to the quiz name and choose "Submissions."

Click on the name of the attempt that you want to view. If there is only one attempt, choose "Attempt 1."

The information that your instructor has setup to be released will be visible to you. This may be a simple confirmation, your score, or it could contain the questions and answers. Once you've reviewed the submission, you can close the window to return to the Quiz tool.
