At the end of a quiz, Canvas will attempt to show students their score even if not all of the questions have been graded. For example, in a mixed quiz, the multiple choice and True/False questions will be graded instantly while the short answer questions need to be reviewed by the instructor.
However, this often shows a score that is frighteningly low! I took a quiz with 1 multiple choice question and 8 short answer and had a mini heart attack when Canvas told me I got 10/90... with a tiny footnote "some questions not yet graded."
I propose that for mixed quizzes, Canvas report something like this:
10/10 points instantly graded
80 points not yet graded
