I am very sorry to report that we are having issues with the scoring of
some of the quizzes. It relates to quizzes that have multiple versions. The multiple versions relate to errata where we fixed a question. We have a bug in the system right now that is not grading the quiz attempt accurately. We are aware of the problem and are working to correct it as fast as possible. I am very sorry for yours and your student’s inconvenience. I know how important the scoring is.
