I must say there are a few things, particularly for air law, that the Trevor Thom books don't seem to have in them.
Sometimes things that are asked directly in the confuser are subtly hidden amongst other paragraphs in the books.
What the books do is put air law in context so that you have a better chance of remembering it-not just for the exam.
Don't just try to pass the exam.
Give the air law some respect, some of it could save your life some day!
