If you're doing the JAA ATPL theoretical exams, the best advice I can give you is to get your hands on as much current/up to date feedback as possible. As I understand it, the exam body is only required to change four questions within the subject's database each month. Typically with a database of three to four hundred questions it really doesn't make a huge difference. If I were you I'd contact cadets from big flightschools, like flightsafety, oxford, western, jerez, etc etc... see if they can send you some... Might be hard convincing them to send it to you, but worth EVERY ounce of effort I reckon. Plus talk to guys at Bristol who have done their exams recently and see if they have any.
Ok, obviously learn the subject, but to be honest in my opinion that won't guarentee you a first time pass in everything. Some of the questions are ridiculous and you'd only get the lot from learning the material AND having seen the feedback.
Good Luck
