On a somewhat related note: for my maths exam today, I used some additional paper for working out on one of the questions. I slipped this sheet in between the pages where the question was which I had needed the working out paper for. I did specify which question the working out was for and, just in case, I included my centre and candidate numbers on the spare paper. Will this be scanned in and marked, marked in an alternative way, or will it remain unmarked... ?
