Hi Mike!
I used aviation exam aswell, I cant recall so much new questions, maybe because they were familiar from avi exam, or from the books or university studies.
From FPL there were a bunch of new (bristol books helped me there) but from Radnav, there was one new only.
There are rumors that a new bunch of questions are coming up soon, but I dont know more about that.
You can sit Austrocontol exams in Budapest aswell.
