DS is in Year 11 and school use mostly AQA for exams. However, it's looking likely that for health reasons we're going to have to withdraw him from school, and just enter him as a private candidate for core subjects next summer.
However, the only exam centre around here offers EdExcel, and a few OCR. Is there any difference? Surely maths is maths, Romeo and Juliet doesn't have different versions etc etc?
