Thank's for the replies, especially LVL_CHG. I think it actually is the 3 finger rule, but a friend of mine must have just added IAS in there somewhere too. I think i actually finally understand it now.
And to the two or three people telling me to just "simply learn the content".
To be honest, with the small amount of time i've had for the 7 exams i'm taking in June, reading and understanding 7 enormous books is the last thing on my mind, especially when english is not my first language and i've always found myself reading longer on an english book. It would have take me more then 4 months just to get through the books.
I understand that i am not just studying for an exam, but also for a career (which is quite a silly statement, because in every profession this also applies), but for now, whilst i have to deal with the CAA and their total incompetence when it comes to setting up/creating a decent (and i do not mean easy, i mean understandable) exam, "understanding" the work is the last thing on my mind, because the last time i tried that... it did not end well.
