I accidentally included a T/F quiz question on material we haven't covered yet. I set up the quiz to draw a certain number of items from a Quiz Bank, so not everyone got this question, so I don't want to just give everyone credit. Is there a way to make both True and False correct for this question? Or to somehow give automatic credit to everyone who got this question on their quiz?
Also, if I change this in the Quiz Bank, will it change the correct answer to be either T or F for students who took the quiz, if the quiz is now closed?
