Hi Hoduka,
I will probably sit my exams in Hungary too!. what I am doing so far is going just thro aviation exam and try my best to understand the explanations for every question not only for those I get wrong. If still there is something that is not fully clear I would go back to the books. I am using Aviation Exam because it has way better explanations,than any other question bank Ive seen. Would you recommend AE for the Hungarian NKH too, did you see many new questions (those from the ECB4)
thanks
