I find maths relatively easy, language a little less so, but a couple there had me thinking for a while - quite tough for the average eleven year old I think.
Was only looking at this as I think it was in one of the big weekend papers that one of the questions in Maths GCSE O level this year was along the lines of
1. Write the number 500,000 in words.
Kind of ridiculous I thought, I'm sure it was like most examples in that it was hand picked to make a point but did seem silly easy for a serious exam
pretty much along the lines Jon said..... dunno if it's the same now, but when i sat my GCSE (semi not ancient brag) there were four different papers - 1 being the hardest and 4 being a piece of piss (with questions like that one). If you sat the higher level you did papers 1 and 2 and could attain an A-C grade or a U, intermediate papers 2-3, where 100% would bag you a grade C, and foundation level (3 and 4) where the highest mark you could pick up was, I think, an E grade.
