Hi, @js17k , ericwerth has given you great advice. This is something I had to plan for when I first started building my courses, so I thought I'd chime in to share my experience. Total points possible for a Canvas quiz stems from the total value of the points for the quiz questions; in other words, it's not currently possible to apply an overall, or top-down, point value to a quiz. So, when I built my quizzes in Canvas, I manipulated the point values of the individual questions to make them add up to 100. This had a two-fold benefit: it allowed me to make all the quizzes of equal value, and I could mimic a percentage in the Gradebook (since quizzes don't display as percentages, only as points). And it even had a third advantage, in that it made me evaluate each question individually and decide which ones should contribute more to the total, and which ones less, depending on where the questions fell in the Bloom's Taxonomy hierarchy.
To save some time, you could edit the quizzes by dragging all of the questions into a single question group and applying a point value per question that would add up to 100, keeping in mind that this will also have the effect of randomizing the question order (How do I create a quiz with a question group to randomize quiz questions? )
The good news is that in the new quiz tool, Quizzes.Next, it will be possible to apply a point value to the quiz without having to adjust the points for the individual questions, and you will also be able to display the grade as a percentage.
