I trust both of you are doing the PPL exams in english, right?
Regrettably I have no info about whether the english version is just a direct translation of the hungarian version, or something completely different..
I was advised my school to do it in hungarian, citing that the "english translations are bad and the questions hard to understand".
As for the hungarian, I did the exam last year and approximately 80% of the questions were from the bank on pplkonyv.hu (cannot post links).
