AFMKaplan Question Book in Addition the the BPP one

Hi All, I'm lucky enough that my work puts me on a revision course that is a week long. Unfortunately (or fortunately depending on how you look at it!) we work through most questions in the study text. We use the BPP material, which is good but as we cover most of the book in the course, is it worth buying the Kaplan book for me own independent study? Don't want to was the money on a new book if i wont use it. But if it proves to be useful, i'm in! Thanks all, Ben
