I looked at the stuff from the BCS and it didn't seem very difficult, course or questions.
Do you have to take courses or can you just go to your local test place and sit the exam?
I don't think the Jobcentre will stump any money as when I mentioned it, they said they have a "special" fund for exceptional cases.
It is something I can do and it may help - suppose I haven't got anything to lose by trying it.
