Does anyone know what the failure rate is like at stage 2 ? Im sure I read somewhere that about 55% of people who pass stage 1 also pass stage 2 ?
With respect, who cares? At all points during selection you're competing against a standard not between other applicants.
As I understand it I think 3% of those who apply get through selection to training and of those, 90% fail at stage 1 and probably half at stage 2 and another half at stage 3.
