I have been an invigilator for several exams for large classes. I am not formally affiliated with the classes.
One thing I routinely notice is that, despite warnings, there will always be some students who will very quickly and brazenly flip through the entire exam (booklet) and look at the questions before the exam starts. Some will do this very quickly to get a sense of the type of questions (no more than 10 seconds).
What should be the appropriate response to this type of behaviour? The dilemma for me is, I don't want to expel a student for a less than 10 second glance at an exam, but I have been very annoyed by this type of brazen behaviour (even when I was an undergrad), which clearly constitutes cheating.
Can someone please provide advice as to what to do for this minor type of cheating behaviour?
