The Overall feedback feature in a quiz will automatically display a general message to students after completing and submitting a quiz. The displayed feedback is dependent what the student’s grade on the quiz is.
The quiz setup area has five preset areas for Overall feedback, and all or none of them can be utilized. The two default boundaries are 100% and 0%. Any feedback in the first area, without creating other internal boundaries (i.e., 90%, 75%, 50%), would then apply to all students that completed the quiz.
