@Pauzo hmm you have a point. But I don't think it's that. Don't you find it strange that the examiners seem a little too lenient towards the examinees? Not only are they allowed to show themselves to the examiners every few hours but are also free to take and reply to questions asked by the examinees. The only 'warning' they get is their ring blinking red. Isn't that too lenient? You'd assume the system would take more precautions if they had to erase memories just because an examiner broke rules.
