When I was a flying instructor one of my students failed the PILAPT test for one of the major schools and it hit his confidence as it has yours. I don't put to much credence in these tests as I can honestly say that he was the most naturally talented pilot that I ever had the pleasure to teach. He is now completing a sponsorship with another organisation and I am sure that he will enjoy a long and sucessful career. Give it another go, pass marks go up and down depending on requirements, average of those tested amongst other things. The only way you will know if you have what it takes to be a pilot is to get yourself down to your local airfield and have a trial lesson (if you haven't already). Get your hands on the aircraft and see how you feel. I have seen many people who were heart set on a flying career who just found that it did not agree with them. Try it out.
