I passed mine last Friday (Aug 20th) but I got accepted and filled in my security questionairre on the 6th of July. It could be that the delay for your start date was pending security clearance, whereas mine may be already cleared (wishful thinking maybe but I don't like the thought of having to wait 6 weeks).
Has anyone else had a chance to specify Aero or Area or does everyone get streamed into whichever course they are best suited to? I would much prefer Aero.
