I think Sapperkenno has a point. The aptitude tests are there for a reason and failing the same one twice doesn't bode well for the OP. Personally, I find the flying through boxes to be the easiest one, I've gotten 10 10 10 on this before and have never gone below 9. I'm surprised that anyone can fail it to be honest. All it takes is some anticipation and a quick grasp of the joystick sensitivity. If the OP is struggling with this then I highly doubt he is a first class pilot as someone else suggested above.
Out of interest OP, have you done any actual flying as a PPL or taking lessons?
