I got through by just simply being myself.
There were 25 people in the group, and 15 got through to final, which was great to see. They have heaps of jobs available, so seem to be willing to take as many as they can get, if you meet their criteria.
All the info you could need is provided in the tests. I had heard that you needed study up on company info, like fleet info, and key dates in history, but that wasn't on todays test.
Practice PA's if you are not a confident public speaker. Read magazines outload, and try to think up random PA's.
I am feeling very confident about this, so am praying to god that I can finally live the dream, and become what I know I was born to do.
Good Luck!
