I stuffed up on one question and I know you can override marks on an individual basis. Are there ways to override marks for the whole class on that quiz question?
Change the answer to the question, then "Regrade" using Preview. At that point, you can selectively decide whose grade you want to change. For example, those who got points for it, leave alone and only change those who initially had it wrong. Of course, some of this depends upon your question-type.
The questions type is "matching". So, I play around a bit isn't getting anywhere. I've asked the TA to go and manually override the mark but just wondering if there's a quicker way.
