Be careful. I remember that I got just one question wrong in my M&B exam and it cost me 9%. Yes I did say 9% for just one question. Its marked out of 33 marks and the one I got wrong was one of the higher value ones worth 3 marks. To add insult to injury I was just at to handing up my paper and walking to the door and the answer just popped into my head. I was like a bull for the rest of the day !!!!
