It's been a few years now but:
Usually your flight route will be given to you the evening before, so you have plenty of time to plan your route. Just call for a weather briefing in the morning, and get the winds aloft etc, to complete.
You'll get the oral first, then the check ride. This helps you get to know the examiner better before the check ride. In the U.S. this is fairly informal situation. Study those area's where you gave the wrong answers on your written, the examiner will start there first. My examiner was a very experienced female, if you did not give the answer that she wanted to her question, she restated it another way, by asking another way she gave you another opportunity to give the correct or complete answer she was looking for.
Know your airspace stuff :-
What class air space are you in here?
How high/low can you fly here? Several of those, especially under class B airspace or over class D and under class B. (I was asked about some places in South Dakota that are class E up to 18,000ft.)
Know your map symbols.
Know the runway length at your planned destination airport.
Know how much fuel your engine uses per hour, and how much total flight time you have.
During the check ride, if your not sure what they want don't be afraid to ask. (My check ride pilot asked for a stall done from a straight and level flight condition, I had never done that before)
Use the check list, make it obvious that you are.
Yes they want to pass you, but they also want you to be safe. Don't do anything really dangerous and you'll be fine.
Regards, and Good Luck,
