I have recently come across a bug whilst using a letter grading standard which uses the letter X to represent a fail as well as E - Excellent G - Good and S for satisfactory. When the tutors enter the grade in the speed grader view it defaults back to X rather than the grade they entered however in the grade book view the grade shows up correctly. We have not assigned any points to the standard as this is for a diploma program using letter grades with no numerical value. We have used this method for several assessments previously so this bug has only occurred recently.
