I had a quiz with 105 points already graded. I wanted the total grade to be 100 and have 5 bonus points. I therefore edited the quiz by changing a 5 points question to 0. So while the total is now 100, all student's grade is unchanged. I would like now to have the grade posted on canvas but it seems that I have to go back to speedgrader and individually scroll down the quiz and click "update scores" for all 128 students. What a waste of time. Is there a way to validate all grades at once?
