Was this a CEM paper? If so there will have been five sections in the paper with each section clearly marked separately on the answer sheet.
Surely she can only have gone out of sync on one section?
Did you make sure she knew how to use the answer sheet before going into the exam?
Did you explain to her about the role of the invigilator in the exam?
Once she realised she could have put her hand up and asked for help. They might well have give her a blank answer sheet which would have been quicker than having to change all her answers.
I suggest you send a detailed email to the school explaining exactly what happened so your notification is on record should you need to appeal. DG
It was a CEM paper and was indeed in just one section,[test content removed by Moderator]
Unfortunately she didn't realise until it was too late and I think panic set in.
Although we have spoken to the school head, it is a good idea to document by means of the email as you suggest and will follow this up. Thanks
