Follow these steps if after you have already activated a quiz and it has been taken by students, you realize that you left an answer blank so students are getting marked off for the correct answer:
(1) First you'll want to go in and enter the correct answer in the quiz itself so any future quiz takers won't get marked off for choosing the right answer.
(2) Then after you do that, you'll have to go back into grade quiz (the ruler with the green check mark) to give points for the correct answers for that question.
(3) Then click on "attempt 1" for all of the users that already took the quiz and were marked off for choosing the correct answer. You'll see that D2L shows, in red text, "Note: This question is an old version as it was modified after the quiz was taken." for each student that has already taken it.
(4) Under that, you'll see next to the score box that it says "not autograded: a default value of 0 was assigned." You can just change that to 1 (or however much the question was worth) and then save. They now have gotten credit for the answer.
