My sister just sat her edexcel English literature paper 2 exam in the morning and she came out crying accompanied by 2 other teachers. My parents have been informed that an invigilator detected a post it note, presumably one of her notes from revisions, on the back of her arm towards her shoulder near her deltoid muscle. She was unaware of this note and she had absolutely no intention to cheat. She is now almost certainly going to get 0 marks on this paper but we are worried about her other gcses. This includes edexcel maths and the school said in the worst case scenario she may have to resit all her exams in november and will not be allowed to come back for sixth form. Is there any way to appeal her innocence? And how will this affect her near future? Any advice will be appreciated. Thanks
