Hi wolf141,
The stuff you see on latestpilotjobs as preparation for the adapt test is sufficient. Nothing much you can prepare for. I'm sure they must have sent you the package already. Just be yourself and answer as much as you can. Remember the adapt test is a personality test. No so much of flying skills as those will be assessed in the simulator. You will be flying 'missions' as they call it. But all will be explained to you beforehand, with a practise run before you start. Just a matter of how you keep your calm, prioritise stuff you do, etc etc.
Good luck. Did mine in feb...
