The I.A.A have a new question bank, rumor has it the get it from the Dutch. Bristol was a great help for I.A.A exams and still is for setting yourself mock exams, but trust me dont go into the exams thinking that if you have memorised ever Bristol question you will Ace the exam it used to work but not any more. Just put a bit of time in and study the books it will pay off in the long run
