I have a quiz that the students have already taken. I would like to change two questions such that they are worth zero, and any students who got any amount of points >0 on them get those as bonus questions. For the one question (a matching question) I was able to do this by making the question simply worth zero and then re-grading, and I can just use the fudge to give them the number of points correct they originally got.
However, the second question is a short answer question. I want to a) change the value of the question to zero, but if I do that in quiz builder it doesn't apply to quizzes already taken, and when I try through the speedgrader, there's no option to do so.
How can I do this?
