Having just been to OASC (early November) the best piece of advice i was given by the guys on this forum was - Don't bull****. The boarding officers can see you coming a mile off and you invariably look a prat! If you don't know say so.
Also - know your current affairs - they are looking as far back as 18 months ago -don't bother with Afganistan they've heard it before and are not really interested.
Above all don't crack under the pressure and have fun - this might seem an odd concept but it can be quite a laugh once the interview is out of the way. Good luck
