Not sure about Edexcel unit 3 maths. I think the boundaries are fair considering that the paper was the easiest so far, but I made some stupid mistakes (although I did think this about previous maths exams) and this means that I might only scrape a B in this exam. After going through the exam when I did it I thought I'd get about 55-60 marks on the paper so that should hopefully get me to 116 UMS to average to an A overall. I really hope I'm not one mark off or something annoying like that...
