During the maths exam on Wednesday I missed when everyone out their information on the front of the paper and so did it rushed once the paper had started. I definitely put the centre number on there but I am worried that I didn't put anything else. I am almost certain that I did because it's the same as every other exam paper. What would happen? Would they be able to work out that it is mine due to it location in all the other papers when they are checked before being sent off?
