Funding Help

My daughter has aspergers and clinical anxiety she now 17 yes old. She didn't manage to do any GCSE due to anxiety and started and stopped college after a few months as couldn't manage one day a week. She on meds that's the only thing chams get involve with. They said she won't be on the child mental health much lionger and education people have given up on her. She thinking of online study to do her GCSE but its costs 280 per exam which as a single parent can't afford. Feel totally lost
