Is there a way to force a recalculation of the grade book? I am in Moodle 3.6 and there is a course that had one student whose grade was not calculating correctly. She had an A on the first exam, there was a second exam listed, but no grade, and had a 0% F in the Exam category. I fixed it by changing the aggregation type from Natural to Weighted, but now teachers are worried that they will have to thoroughly check grades to make sure Moodle is calculating correctly.
I did just change to have Ajax turned on for the grade book for all teachers, maybe I shouldn't have done that.
