KF,
I should have probably made it slightly clearer, my apologies.
I have to take an A.S.T (Airman Selection Test) to determine whether I have the right aptitude for WSOp.
If successful, I shall attend the P2 presentation and after that if I wish to continue with my application, book my Filer Interview.
OASC still do their own Aptitude, Medical, Fitness & leadership training, I think the AST is a new test that has been taken (Please correct me if I'm wrong).
All the best
NDW
