- * status should be automatically set to 'completed', then the score should be
- * evaluated against mastery_score and, if a raw score and mastery_score value
- * are set, assign the final status based on that.
- * As such, this script will:
- * 1 - check the current status for the given element is still 'not attempted'
- * 2 - check if there is a mastery score
- * 3 - check if there is a raw score
- * 4 - if 2 or 3 are false, change the status to 'completed', else compare
- * whether the raw score is higher than the mastery score. If not, the status
- * will be set to 'failed', if yes, the status will be set to 'passed'
- * 5 - update the status in the table of contents
