There are plenty of people who will give you a good copy of Air Legislation notes for the GCAA for nothing, PM me and I'll put you in touch with someone who teaches air legislation.
...Also be careful with any one who says they have up-to-date questions, some of the questions that people who have come out of the exams and claim to be the latest may have ...lost something in translation so to speak.
I must add that I think keeping notes to yourself because you want to trade is a scummy thing to do! The UAE is a small place and most people are willing to help without being held to ransom ...obviously your one of that minority few who doesn't like to help your fellow engineers, Incidently I have the notes and questions you need.
