Why do quizzes in Moodle have strange assessment scores or percentages that do not make mathematical sense?
This is an issue peculiar to Moodle. Unfortunately, we do not know of any settings that will make Moodle score in a logical way.
We provide a very limited amount of information in our IMSCC (installation) file about each question:
- the question itself
- the answer choices
- feedback on each answer choice (right or wrong)
- a scoring basis of 1 point per question
Moodle then does some calculations on that, computes "marks" in addition to a "grade", and comes up with strange numbers we cannot consistently explain.
Unusual scoring scenarios do not exist in all Moodle installations, leading us to believe that some Moodle administrators have modified their default settings in a way that circumvents this problem.
We encourage you to reach out to Moodle's support community for assistance with this issue. If you are a Moodle administrator with information that can assist us in meeting Moodle's standards or explain how Moodle's scoring works, please get in touch with us.
