Having decided upon the remaining settings for his quiz, familiar to us from Moodle 1.9, clicking on Save and display then takes Andy to the question making area where we'll follow him now:
Question Bank contents: This takes us to the categories and list of questions already made (if we have some) that we can choose from
Maximum grade: The overall grade for the quiz is scaled to be out of this total
Add a question…: This takes us to the question set up for making new questions
Add a random question…: This allows us to set up the quiz so that when a student starts a new quiz attempt, a question is chosen at random from a particular category in the question bank
