Phone the examiner, ask what they'd like you to prepare on the day, they're human, they'll talk to you, likewise, ask your instructor.
I'd assume W+B, take-off and landing within specs.
You should also brief them with your standard passenger brief (the basics, doors work like thus, seatbelts like this, if you see anything near us tell me regardless of whether you think I've seen it or not, when I'm talking or when I give you the bird STFU.......)
