We had to write on the multiple choice answer sheet, but the school number was already filled out for the multiple answer sheet. Also it doesn't matter if you didn't write on the multiple choice question booklet because that's not being marked.what did we have to write our student numbers on? Was it the multiple choice answer sheet and the question booklet or just the question booklet? Also can I check with my school if they haven't sent them away yet? I say this because I remember writing the number and centre number on one thing only.
