Someone at my secondary school only took 5 GCSE's and only passed 1 GCSE (and that was a short course). Apart from the C grade he managed to scrape, the rest of his grades were E's and U's. His worst mark was 1 mark and he got no questions right (he got 1 mark for his working out). Apparently the question was 'name this shape' and the answer was 'An isosceles triangle' but he put 'a triangle'. He got 1 mark out of a possible two.
