An issue has occured to a teacher of mine.
He has a survey of about 20 questions of which the same 5 are repeated 4 times. they are put into context by the labels. It serves as an evaluation.
Now while technically it does work, the teacher has to have a printout of the feedback to make sure he remembers which question numbers fit into which context.
If labels where brought out with the export and/or response analysis this would not be an issue.
