In addition:
Where a flight requires to be of a certain distance...say to qualify as 'X-C (30nm as the crow flies), if it was done outside of the USA, take a chart to the checkride or have access to an online distance calculator. I've seen a picky examiner stop a checkride because the candidate could not verify the overseas distances flown.
Beware of the validity time of your charts and plates. Showing up with expired material is an epic 'fail'. If necessary borrow (photocopy) for your training, then buy a set which will be valid for your checkride.
