I've been experiencing some strange problems in the questionnaire module. I use it as survey for the classes quality. Several questions are in a 1-5 grade and I have been receiving calls from my students saying that they gave my teacher a grade 5, and the system recorded a grade 4, or a grade 3 and it recorded a grade 2. This has happened not once or twice, it happened several times with different students. Does anyone experience such problem?
