Easy as pi?!?

Although I have higher-than-GCSE maths and English qualifications, they are overseas ones and I currently have my fingers crossed that I can prove that they are equivalent to at least the grade C minimum required for teacher training. Just in case I can't, and I actually need to sit equivalency tests in the near future, I did a few practice past papers today and, thank goodness, they were a doddle. Well, mostly, anyway! I hadn't got a clue what was going to be in them so I'm a bit calmer about it now!
