Only one caveat, the language used in the questions is different from what you'll find in the papers.
I agree that the framing of the questions is very important. I have been self-testing using the 'Question and Answer Simplifier' from the JP range of books. Does anyone know if the questions in this are framed in the same way as the actual exams ?
I am hoping to take four of the exams in early January

, so the option of purchasing "JAA PPL Exam Secrets Guides" may be too late for this attempt.
Finally, get the TSA fingerprints done in the UK
I have seen this advice elsewhere, but my FTO says I can get it done at their offices on the day I arrive. Hope they are right !
