Hey stardoggas,
I failed AFPA pretty badly in December and gave myself a few weeks to resist. Passed 2nd time with flying colours.
I recommend knowing the AFT notes back to front and also buy Rob Avery's practice exams. They will show you some different techniques to approach problems that really help.
I also made a lot of mistakes using the incorrect RSWT for the climb data, so I highlighted a line where to use FL185 and FL235. It's a pretty obvious one but it was an easy way to filter out another mistake.
I think the CASA SOP's listed in Rob Averys texts are the most accurate. But also remember the 727 Booklet has a lot of information that they may use to throw you off so make sure you read every page. Know the definitions like block time, etc as these are the little things that will make you waste precious seconds trying to figure out what are they asking.
Good luck with it mate!
