Hi All,
Watch out when using older Air Law books, as they can fall out of date surprisingly quickly.
Incidentally, I reckon that the Air Law exam was the worst of the lot. Whoever created the questions went for the 'tricky-dicky catch-you-out' technique. Complete pain in the proverbial as they don't actually test your knowledge in a fair way.
My advice? Go on then...
Don't just use the books as a mechanism for passing some inconvenient exams. Read the various books carefully, as most of the information in them is highly relevent to flying. More importantly, some seemingly trivial point hidden deep in one of the books may well save your life one day. (Sorry about the drama).
Next, buy an up-to-date PPL Confuser. That will ensure that you actually pass the damn exams.
