boy in DD2s year left his phone in his blazer pocket during a Chemistry GCSE exam, for whatever reason they were particularly late starting (and so finishing) and his phone bleeped with a text from his mum asking how the exam had gone
.
As it was genuinely a mistake, the school supported him in the invigilators reporting, and allowed him onto the A level course (he had his whole Chemistry disallowed). But, he had to resit the GSCE along with the AS, AND he had the piss ripped out of him for the whole of his 6th form. No-one else for the next two years forgot about leaving their phones switched off
