dronehawk,
The pass rate is really high. There were six on my flight grading and all six of us got through. I friend of mine who is also a cadet had 5 and 4 got through. Talking to the cadets in Adelaide, they all pretty much agree. It can be frustrating at FG talking to all the cadets, because they all reiterate the point that it is incredibly hard to stuff it up (which is hard to swallow when you still feel so stressed). Most importantly, you need to have a good attitude and an ability to take criticism. Study as much as you can while your there. They will give you a folder of information... know it well
