Another purchase I reccomend making are the 'Keynotes For Pilots Key Facts for JAA ATPL' There are two books in the series at £20 each and they cover all the JAA subjects.
The beauty of them is that they contain all the information vital for the exams but not in a huge A4 file. It means you can read them easily in front of the TV, or at work if you want to be discreet.
Anyway, they worked for me.
