yeah... be honest when they ask you questions coz the panel know a lot of stuff...e.g. if they ask you something about a particular engine on a specific a/c then if you know the answer say it...if not just say, "i don't know." if you lie to them they will build on your lie until at the last moment they whack you with the truth and then you realise that all the while they're just playing with you....sucky feeling....
also try not to be too cocky.....
