In our previous version of Moodle there was an up and down arrow that, one step at a time, moved a quiz question slowly up or down the page. In this Moodle update there is now the familiar Drag and Drop icon, allowing you to use your mouse to move quiz questions more easily.
To Move a Quiz Question Elsewhere in a Quiz
Enter the Quiz you wish to modify
Locate Actions Menu (gear icon) from the top-right corner of the page.
Select the Edit Quiz option.
Click the move icon 
Hold your mouse button down and you can drag the question up or down to whatever location in the quiz you want, in any page.
Once the transparent question has settled into the desired location release your mouse pointer.
Repeat Steps 3-4 as desired.
