16/20, Quite chuffed with that, seeing as I left school at 15 in 1968 without a single qualification (apart from a Cycling Proficiency certificate and badge !).
17/20 on Maths and I got an A at GCSE 10 years ago.
Made a cock up on the speed a distance question and got all the rest right until 19 and 20. Factors and simplyifying equations was never my strong point!
