Hi - I used the confuser to see how my knowledge was developing last night. I thought my knowledge was quite good regarding aerodromes etc and had been using an old Trevor Thom book. I couldn't believe how many of the up-to-date questions were on obscure ICAO articles and annexes - some based on international operations - is this the case in the real exam or are the first 100 questions or so in the confuser misrepresentative? Guess I need to know all the stuff anyway
