Do not give up hope. A friend of mine passed on his third attempt and I know loads that passed on their second. I think the main reason they make you wait 12 months is that with the long period in between it is more likely to remain a test of your true aptitude for the job, rather than simply getting better at the tests and passing them through learning and practising rather than natural ability, if that makes sense?? Well you came so close this time you should be fine now you know the exact format of the tests etc. Good luck.
