I am lucky as I seem to remember more of the stuff 1 year after the exam than I did while taking it.
Can I remember the threshold for number of seats against fire axes and cabin crew required? No
Unfortunately the answer popped into my head. The cabin crew numbers you do actually sometimes rarely use.
Its the same with the ICAO annexes round Europe they tend not to be an issue. Step outside Europe and you better know the ones to do with pax of who and what you can do or your going to be hit in the pocket hard or gain some time in a local jail.
