I'm with 'Uncle Wal' on this one.
Good 'professional' appearance sets the theme for the test.
Make the effort, but don't 'overdo it' - NO bars on the epaulettes
IMHO.....
Nice white blouse, pressed slacks, and polished shoes would impress me even before you got into the aeroplane.
And, don't forget to talk to the examiner - ask anything you do not immediately understand - most of all - relax - if you can...
ROTSA RUCK for your test - and please do let's know how it went.....
