Honestly, I just called my examiner and nicely asked what lesson he wanted me to teach and anything in specific that we might go over.
Spent most of my oral on the minor stuff but he wanted large teaching details on stall/spin awareness, weight & balance and all emergencies...especially emergency landing.
Just please go into your checkride comfortable that you'll pass. It sucks that there's always that one moment in a checkride where you freak out you might fail but other than that 5 second panic....they want you to pass. I told myself everyday of my 45 straight days of studying...it's my checkride to fail.
Also, I learned the most from my CFI-A checkride as well. Best one I've taken so far. My examiner also emphasized the point that we really don't know a lot and it's a continually learning process. Ended up asking me tons of engineering questions with the Cessna 172R and why certain things were constructing and located on the aircraft the way they were. Of course being on a checkride I started guessing rather than saying "I don't know" and he just looks at me and says "really, that's what you're gonna tell a student " and I said " No, I'll probably just say I don't know" and he said "okay, tell me you don't know"...kinda just proving his point that we aren't perfect and don't become a cocky CFI that thinks he knows it all because nobody does and those are the ones that cost you.
Anyways, good luck!
