I failed AFF level 4 four times. After first try, to keep myself from quitting, I blamed all on my JM, on third try I realized that was somewhat my fault, after the forth - that was just wasting of money (except for canopy practice). In four jumps I had 4 different JMs and it was apparent that my skydiving future was in big question. Took my last option and went to wind tunnel in Orlando. First 5 minutes in the tunnel fixed most of the errors and gave me a lot confidence (actually I took an hour, but that was really unnecessarily). After passing level 4 my JM moved me up to the 8 and the rest was easy. Without the wind tunnel there was no way for me to pass AFF. Just my 0.02
