My son is currently studying for GCSE's. I did consider IGCSE's, but the schools that are willing to accept him as a private candidate do not do them.
English, History and Physics all carry coursework, or a controlled assessment; which the schools won't moderate for external candidates.
So, I'm wondering how others have managed to get coursework moderated.
I'm aware of the likes of Oxford home schooling, but their prices are a bit on the steep side.
