Each row represents an assessment attempt. If a user attempts an assessment twice, only the most recent attempt will appear.
Questions and answers are reported in the order presented to the Student. If an assessment includes random questions than each line in the results will report questions in a different order (question 1 for one Student may be question 5 for another Student).
Survey results will not show user data for each attempt.
Results from a user with a course role of Instructor, Grader, or Teaching Assistant will not be reported.
