Draw the wind arrow on your map.
Two issues with that.
1) This assumes that you have a new map for each trip (or use crayons on laminated maps)
2) It also assumes that the wind will *never* change. As an average skills test takes 90 minutes, that means there is easy enough time for the wind to change direction.
The examiner isn't expecting perfection, just wants to see that the candidate is in full control of the plane.
As for EFATO, isn't that always on the cards? Have spoken to a few of my fellow pilots and all of them confirmed that, 500 - 700 feet up, the examiner called "engine failure", pulled the throttle back to idle and asked "what are you going to do now?"
But what is also good to refresh yourself with are your emergency procedures because the chances are, he will ask you the memory part of the lists - ie, what are you supposed to do if there is a fire, engine failure before take-off, etc....
