If they have taken your access while you are supposed to be doing an ICT GCSE then you should raise the problem with whoever maybe concerned (E.G. The school head, or your ict teacher if they don't know about it) because its a legal requirement for everybody to be at grade C or above standard before they are 18(i think thats the age) now in the UK.
And believe me, getting a C in your GCSE is alot better then not and then having to do super patronising key skills
