Dear James,
I had the same question, I rang the board last week and basically said I don't have anything from Uni, nor could I get my IST signed etc as I now live in Oz and they were done in the UK and about 7 years ago. Basically they said that was why they had brought in teh self-declaration form (pieces of evidence) form so we basically have to declare all the work we have personally done (it is int the application form bit think). That way they are basically trusting that you are telling the truth about the work you are supplying as being your own....Does that help?, made life alot easier for me,
Take care, Claire
