A Level Coursework as an External Candidate

I am doing some A-levels during my year off and have reached the problem that wo of them of them require coursework (English Lit and Lang, and History). While I have been able to find centres where I can sit the exams themselves, I am struggling to find centres that will do the coursework part for me as well as the exams. Has anyone dealt with this before/managed to solve this, for instance is it possible to be registered at the centre for the exams (if that's the right word) while at the same time using a tutor to do the coursework bit and then submitting that (for instance)?

Thanks for any help
