NOO ITS NOT UP TO THE SCHOOL!! In fact the teacher's not allowed to do that and he/she HAS TO submit an equal first. The Board of Studies says that teachers are unable to mark accurately to decimal places so therefore they MUST round up or down final marks. In other words, your teacher has to ignore your 0.25% difference and give you equal first, Board of Studies rule made clear by our teachers. Just remind him/her about that and they've got no choice.
