Doing GCSE Dutch out side of school?

I mean, my school don't offer it but I really do want to do it as it is my language but I will need to blow some dust over my language because I haven't used it properly.

It's absolutely possible, but you need to sort out examination centres for the coursework and final exams.

Giving me so much hope

I'm pretty sure most schools can help people with this. There are other people I know who also did the languages they speak at home. I don't see why they shouldn't let you do it. I think there might even be places that can let you do the exam, if your school doesn't.

Found these, I don't know if it will help you:
