Students can flag a question for review: Clicking on the "flag" in the box next to the question puts a temporary marker on it. A flagged question is shown with a red triangle at the top right. It also shows up in the "Summary of Attempt" screen. See https://docs.moodle.org/32/en/Using_Quiz#How_students_take_a_quiz for more info.
