Hi all! If students fail to take a quiz and I input a 0 manually, can they take the quiz and override the 0? That is, will the 0 be replaced with their grade? When I finally open the quiz to show the answers, I do not want students to be able to take the quiz and override my 0 (I put zeros in the grade). If they ask a fellow student for the answers, they would be able to take the quiz and get a perfect score. I am trying to avoid that and am hoping the zero stands.
