I understand about how questions in question groups are randomized when a quiz is presented to a student. However what I'm asking about are when and how are the questions in question groups randomized as they are stored in a given quiz? I created a quiz with question groups, selecting questions from a publisher's testbank. I then was going through my quiz to clean up some of the formatting, sequentially from top to bottom, and got about halfway through, and saved my work. Coming back a day later, the questions are now in a completely different order, which was unexpected.
If there is something that I can do (or not do) to prevent that behavior, I'd love to hear about it. I'd really like the questions to remain in the order initially given, or the order that I give by manually reordering questions in a question group.
