We have gotten this request a couple times, although today I looked to see if there was an idea already. Someone would like to limit the number of questions per page in a quiz, instead of one or all. So let's say you have a 30 question quiz, they can have 10 per page for three pages, so students aren't scrolling through long lists of questions (but also not clicking one at a time for a long list of questions).
I looked at a lot of the Quizzes.Next documentation and ideas, and I couldn't see this one on there, so I thought I'd submit it.
I did see this one: https://community.canvaslms.com/ideas/3912-add-option-to-display-questions-by-group-in-quizzes and I love the stimulus questions in Quizzes.Next, but this is more about pacing or not overwhelming a student with 30, 40, 50+ questions on a single screen.
