TII,
Dont worry, many people fail the 1st test. Keep applying again and your name will be queued up again. Cooling period about a year though.
In '74 when we applied, there was no such tests. All we had to do was continously pat our forehead with the left hand palm, while rubbing our abs (in those days they were abs, now ponch) with our right hand palm in a circular motion. After a few times, change hands. If you can do this, you'll be alright.
In the mean time play some computer flt simulation games that makes you practise some form of coordination.
Keep trying and trying until you run out of age. All the best and good luck.
