Since this is a quiz component, I expect that the user should be shown not just a score, but their score over total and percentage. I think this should be shown both after taking the quiz (perhaps at the top and bottom of the page) and also on the view that shows a list of quizzes that have been taken.

For example, if a quiz has 10 questions, and the user missed one question, it would look like:

Score: 9/10 Percentage: 90%

Is there a way to show total points possible, and percentage correct?
