I created a quiz out of 26 points, but after some students already completed the quiz, I realized that the quiz held much less weight than the previous quiz out of 100. I understand why that is the case, but thought it would average out the percentages not the total points. So, I went in and changed the points per question. Now, students who took the quiz before this change appear to have failed. I can't figure out how to get the quiz to regrade based on the new point distribution. I did not change any of the questions or answers and they are all either multiple choice or multiple answer. Oddly, one of the 11 questions regraded itself, but the other 10 did not. I don't know how or why only one of the 11 did that. But, that oddity gives me hope that there is a way. Please help!
