Hiya! Im not sure what exams boards your with (other than edexcel for italian), but on the AQA website they say:
"Distance Learning Providers (DLPs)
Distance Learning Providers (DLPs) that are registered and approved by us are able to make entries. Where applicable, the DLP will supervise, authenticate and mark the NEA element of the qualification.
They will work with you and us in allowing you to sit the written element of the qualification at a school or college in the UK which is closer to your home.
At present we have four DLPs registered with us:
National Extension College
ICS Learn
Oxford Open Learning/Oxford Home Schooling
LearnOnline Pembrokeshire College"
So the ones listed are legit and not fraud i assume - i dont know if they offer the exam boards your after but i just thought it may be helpful if you considered looking at these ones too
I hope you get it all sorted, good luck with it all!!
