In the Moodle page, click on the quiz icon for the specific quiz you’re taking. Click “Attempt Quiz Now,” then “Start Attempt.” Answer the questions according to the question type. Make sure for a “short-answer” question there are no typos or unneeded capital letters, punctuation, or spaces, or the question will be considered wrong. When all the questions are answered, click “Next” then “Submit All and Finish” and click the confirmation button. The grade should appear on the screen under Grade/100.00.
