DD has had a huge shock after getting her 'mock' iGCSE results. She's year 10, previously sound results for her class and homework but got nothing more than a C in recent exams. We saw her tutor who said all her teachers think she's great - hardworking, a pleasure to teach etc which has always been the situation, no problems with her attitude or behaviour throughout school. They say it comes down to poor confidences and simply nor remembering the stuff. We know she revised, ie lots of disappearing upstairs, lots of post-its and notebooks about the place as has been the case in other years. We help her if she asks but generally let her get on with it. She says there was stuff on the papers that hadn't been covered. She has CGP guides and access to recommended websites etc. Does anyone have experience of anything similar or any revision techniques to share? Keeping smiling and being encouraging but hate to see her so disappointed.
