Fred R,
I agree with High Wing Drifter. I did most of my studying from Trevor Thom's tomes but the best money I ever spent (that didn't involve burning it in an engine) was on the PPL confuser. Have a read through and study of the text books, then before the exam hammer the confuser - you won't regret it (and I'm assuming they've updated it for JAR as I'm a CAA licence holder).
