1) Interviews/Medicals and everything done after the aptitude tests is done in the green overalls (except the PJFT): True! So dont do what lots of candidates did at my course and take 3 suits with you lol waste of space, just take extra sporting gear to wear under your overalls.
2) All Aircrew have to do a Swimming test: False! they will asses your swimming ability at either RAF Halton or Cranwell at IOT, if you pass OASC;).
3) Candidates going for Branches which dont require aptitude dont have to sit the tests: False! Unlucky! If you thought you could stay in bed just because you were going for Rock Ape Officer and not Pilot think again!

If anyone wants anymore rumours that you've heard finalised just let me know!
