Out of curiosity, and considering the big push now for AR in some corners, what is the approach to this stuff? I suppose this is more directed at younger students, but it applies everywhere - classrooms, exams, activities... It generally remains pretty obvious when someone is using a device now, but that may not be the case for much longer. And then there are watches and other items that have been around for a while. Like, is there a no smart watch policy when you take the SAT now?
