So my son has been accussed by his school of plagiarism in his NEA coursework. They have reported him (and others) to the exam board for use of chat GTP. They have been advised they must submit a mark of 0 whilst it is investigated- he has scored 17. He said when they were given the coursework back any parts suspected were underlined in red and for him it was a couple of sentences, for others much more he says.
What are his chances.
