DDs GCSE exam was 1 hour and 45 mins. The invigilator asked the kids if they had finished to which DD replied yes, as she had answered all the questions (ASD) but planned to use remain 20 mins to check answers. They immediately took the paper away and ended the exam early as she was the last one to stop writing.
I have made a complaint to the school but they are being dismissive and fobbing me off.
What can I do?
