Quizzes in which all questions are toggled to "Bonus" do not publish any score to gradebook
We had a faculty member notice some odd behavior recently: while attempting to make an extra-credit quiz, they toggled all of the questions as bonus questions. When attempts are submitted on this quiz, no points appear in the gradebook, only showing a dash (-):
Checking the student's submission shows that it did record the number of questions correct, and shows the total out of a maximum of one point:
However, the quiz has no impact on the student's final grade. Obviously the ideal way to create an all-extra-credit quiz would be to check the "Bonus" option on the quiz in the gradebook, but I can see how someone could reasonably assume that setting each individual question in the quiz as "Bonus" would have the same effect.
I did some testing to on this issue, and can confirm that the same behavior occurs whether or not any combination of the "Bonus" or "Can Exceed" options are checked on the quiz.
This is a pretty niche use case, so I'm not sure if it qualifies as a "Known Issue", but I couldn't find it mentioned anywhere else so I figured it should at least be documented.
