I am about to check in some changes to the quiz layout based on a discussion here at the OU with some of us developers and a graphic designer. Most of the changes from this went into the OU theme, but some of them seemed so obviously sensible that I decided to commit them to the standard theme.
Reorder the feedback under each question on the review page, so all the feedback comes first, and the grade is the last thing.
Fix the layout of true/false questions.
Space out the overall boxes round each questions using CSS, not <br /> tags.
Don't leave space for a non-existent question number on Description items.
Reorder the quiz styles, so all the view page ones are together, and all the attempt page ones are together, and so on.
On the quiz view page, highlight the whole of the best attempt row, not just the score.
Redo the table at the top of the review page.
