Hi Pipergirl
Get to know your whizwheel by heart.
Do your utmost to fly accurately.
Get your emergency procedures verbatim.
Get as many backseat flights as you can, starting now.
Get in a few IR practise flights and get as much practise with VOR,ADF, DME,etc beforehand.
Get sharp on the RT work.
Every flight you take has to give you a lesson. Don't just swan around. Practise timed turns, steep turns, ADF and VOR tracking and every landing has to be as good as possible.
Get the CPL flight test syllabus and try each individual item until you are certain of them.
regards
TDD
