G'day dude,
I sat it a couple months ago, used AFT notes and also extra Avery practice exams. Studied about 2 weeks. The AFT notes are excellent and cover everything you need. There is some more complex stuff in the Avery exams on map stuff which I had NFI about, but never saw any of that in the exam anyway.
There is an even spread of both the theoretical knowledge stuff and also the calculation questions (bigger marks) like PSD/ETP's etc toward the end of the exam. I did find I was running out of time and by the end I did not have enough time to accurately calculate the last complex big mark question. Still got through even though I believe I got it incorrect.
I think it's always pot luck what type of questions you will get, but I will note I had 3 very complex ETA / ETD time questions based on curfews where you cross the international date line including a layover delay at another enroute port. Make sure you can work these out accurately while under time pressure. You can easily muck them up when working under pressure. They were worth 3 or 4 marks each so you do not want to get them wrong.
Good luck
