Basically, I'm in Year 11 and I bought this CGP book for revision for my final exams:
However, I've just noticed that the one I purchased said it was published in 2006; and I found another on Amazon which was published in 2011:
So I was wondering if I should buy the newest one, or if it even matters? I've been getting B's in all my Science exams and I want to revise effectively to bring my B's to A/A*s.
I forgot to add that I began year 10 in 2010 if that matters.
