But how was FFF supposed to know these things about you from your first post? Telepathy? Your post gave a very real impression of someone with at least a PPL but unsure about how to do a W&B. The identification of your knowledge was not obvious at all.
Treat the flight test as if you are already a commercial pilot doing just another day's flight and do all those things you know are part & parcel of any flight preparation for that particular aircraft. Good luck!
