In the original post trustno1 mentions that he/she/it already has Jeremy Pratt's book and asks if there is anything else he/shg/it should be doing. The JAR PPL confuser is a valuable addition to the the text books you mention, I would not suggest that anyone who can answer all the questions in the book but has no other knowledge is in any way fit to fly.
In my opinion the academic side of learning to fly is not about learning by rote, but the fostering of common sense coupled with knowledge gained both from text and your instructor.
However I think that it helps to have some sort of idea about what sort of questions you will get, and further more you will see how good is your knowledge of the law before you waste time and money sitting an exam you may not be prepared for. I cannot think of any discipline where mock exams are discouraged.
