Advance maths book, what to do? (ten points best)?

Ok, as far as i'm concerned maths is (by far) my worst subject. I am in one of the bottom sets for it, i am a bright lad and would be in all brainy sets if it not be for maths. I hate numbers and today, after completing set tasks half way through the lesson my maths teacher said "Ok Connor tomorrow i would like you to work from this more advance book. " She didn't give this booklet to anyone else. I'm 14, i have the Edexel booklet6 with me now, and it's really complex stuff. What do you think? Thumbs up to all answers and 10 points to the best :)
