Was there taking a long test and noticed some workers kept hovering around my area and looking at this kid a few seats in front of me. Then someone a little later came and sat right behind him taking a test. After a few mins they came over and asked him to get up and come with them. I think he had been using scratch paper with notes.
My friends wife worked there and I asked her about it and she said that was coming if they suspected someone of cheating one of them would pretend to take a test by them an monitor them until they caught them. She also mentioned two separate workers need to confirm cheating before they will “apprehend” someone. She had some funny stories to tell but I can’t remember them now.
