GCSE exam access

Hi I’m hoping someone can give me advice. My daughter is autistic and sitting her GCSE exams. Nobody offered her any special access arrangements so she’s been sitting in the main hall with the other kids and finding it really hard because of sensory distractions. The school day they can let her sit in the smaller room with the other autistic kids because the access arrangements were made some time ago and can’t be changed now. 

Is there any way I can appeal to the school as I feel it’s unfair she was never offered any assistance and also she didn’t realise about the sensory issues until she was actually in the exam environment. She still has 2 weeks of exams left.
