Elizabeth - If you apply to study to be a teacher in the UK, no matter your age you have to prove your education back to GCSE/O-Lever, you get in touch with your school, they tell you the exam boards at the time, which these days have mostly merged into 1, and you write off with a small cheque and they send you the results you got. It's all there somewhere.
Great stuff Candyfloss. Really glad someone saw this and went for it. Best of luck for your mate. x
