I'm a teacher using Moodle 1.9. I have just executed an online quiz, and have 97 student attempts. The quiz was set to randomly select 20 questions from a set of 150 (which means that in the overview of results, the vertical columns correspond to question "slots" but not to actual questions, as each student got a different set).
Now of course in reveiwing a couple of answers, I noticed a mistake in one of my questions (after the horse had bolted... isn't it always the way) which has stolen a point from any student who attempted it and who got it right... I know I can manually regrade a question, but my problem is this: given the random selection of quetions, I have no idea which students have attempted this erroneous question, nor in which slot. is there any way that I can rapidly identify all the students affected, without having to manually scan each answer for each student (which could potentially mean opening 1,194 popups !!)
(Please don't tell me I should have been more careful in editing my questions... I don't need to hear that.)
Any help would be greatly appreciated!
