How do I change quiz grades to be shown as a percentage versus points?
Sheila, unfortunately this option isn't currently available in Canvas. Yet, there is a feature idea up for vote - Quiz grades as percentages - so my recommendation is to vote and comment on why this is important and would help you!
Sheila, Kona Jones has given you great advice. I've always employed a workaround. I force my quizzes to mirror percentages by fiddling with the points on the individual questions so that the point total for the quiz is always 100. For the type of quizzes I typically administer, this approach suffices; the workaround gets cumbersome when there are a large number of questions in the quiz, and can be tricky when certain point proportions between questions need to be maintained (for example, if the quiz consists of a combination of essay questions worth more points and true/false questions worth fewer points). A different feature idea would allow the quiz designer to select a point total and distribute it amongst the questions in the quiz, and I provide that link here as well for your consideration: Assign a Total Quiz Value and Automatically Distribute the Points to Questions
