A student reported some odd grading on a quiz, which I've since confirmed. The quiz has three questions, and the student's marks were as follows:
Q1: Correct (1.00)
Q2: Correct (1.00)
Q3: Incorrect (-1.00)
...but in the summary of his performance on the quiz, it says:
|Grade||33.33 out of a maximum of 100.00|
Am I missing something here? Any advice for troubleshooting this further?
