Hey schoey
You should at some point receive a letter from PSA saying that your file has arrived their and you are in competition with the other applicants and so on, I rang up PSA the day after receiving that letter and they were able to give me more information on my competitiveness. Mine arrived about 6 weeks after my Assessment Day. I would recommend ringing your manager first so they can confirm your file has arrived their, then if it has I would ring PSA up. According to PSA there are 27 DEO spots left this year (3 courses of 9).
Best of Luck

Is there anyone on this forum who has been to flight screening recently and has any tips on what to expect in addition to what is throughout this thread?
