To access the specific visibility settings for a quiz, first turn editing on. Then, click the three-dot menu to the right of the quiz and select Edit settings from the dropdown menu.

Scroll down to Review Options. This section allows you to control what students see and when. Points refers to students' scores. Depending on your language settings, it may be labeled as Marks. If you uncheck this option for a particular time period, students will not be able to see their score at that time. For example, if Points is unchecked in the "Immediately after the attempt" column, then students will not be able to see their score immediately upon completion of the quiz. If Points is checked in the "Later, while the quiz is still open" column, students are able to view their scores after exiting the quiz, as long as the closing time for the quiz has not been reached.

If you have set a close time for the quiz, the last column determines what is visible any time after that time has passed. If you don't have a close time then this column is disabled.
