Wrong Stuff
Trevor Thom is a good source, but in addition, for JAA PPL you would be advised to read the PPL Course, JAR Supplement by Jeremy Pratt. This is a good book that updates you with all the additional info required for JAR PPL. Aviation Law is probably the one subject that has changed the most for PPL.
Top tip: Get yourself the JAA version of PPL Confuser, by Neung Sornying. It is excellent for revision.
Best of Luck,
ATCS
