Thanks suddenly I'm feeling a lot more confident on this actually! Reckon I got between 85 and 95, depends how many workings marks I get for the ones I got wrong.

Im almost certain that the Sports Centre question was 4 females?

thanks a lot Mr M

hopefully 95+ unless i missed some working marks or logic marks in the * questions

did you need to put 6cm for x, or would just 6 do?

Thank you, Have you posted your mock paper yet?

Out of interest what questions did you get wrong. I got the driving in France question wrong, and the circle theorem wrong, and didn't get the gradient right on the straight line question (stupid, I know). But everything else was fine.
