Would be nice to have a survey option in the exams. If selected, there would be no "correct" answers required and individual student responses would not be visible. (only show the statistics on the answers). The instructor only sees who has completed the survey. Ideally, you could give some credit for completion alone.
It would need to be labeled as a survey rather than an exam so that students would recognize the difference.
Thank you for your suggestion to improve Learning Suite! We are reviewing your enhancement request, and will keep you updated upon further implementation.
