Stage Check (without the mics and spotlights)

So there's this thing we... wow, I can actually include myself in this... we pilots must do which is quite similar to, yet far more terrifying than, a driver's test. It's called (drum roll) a stage check. I know almost nothing about it except that everyone has a sort of hushed reverance and honest sincerity when they tell you about them and it consists of an oral examination followed by, well, basically taking a total stranger up in a plane with you and performing the maneuvers they tell you to do. I have a little outline study guide that's only two pages long and little over ten hours as pilot in command of an airplane and now I have to do a stage check! (I'm including a very adorable video by pixar that most precisely portrays the feelings that accompany such a time as I'm in.
I've been studying my ass off and I still feel clueless. I'm constantly confusing whether I need 5 miles visibility in Class D airspace or 3. And are those statute or nautical miles? I know faaar more acronyms than any one person should ever have to know: TOMATOFLAMES, AV1ATE (yes that's a 1), DRAW Fighter Planes... the list of acronyms is endless. If there's a way to turn something into an acronym or abbreviate it.. oh we do it.
I recite emergency procedures in my dreams "Fuel shutoff valve-on, mixture-idle, fuel pump-off.." I find performance charts everywhere! in all my clothes pockets, in all my drawers... i'm swimming in weight and balance calculations. I check the metar even on days when I'm not flying just because it has the most accurate weather conditions. Life goes on pause the moment I hear an engine overhead, I just have to see it, have to see if I can make out what plane it is. I spend late nights in airplane hangars asking mechanics questions about carburetor intake manifolds. I don't even know me anymore. All I know is planes.
And yet, I don't feel I know enough to pass my first stage check... I'm going absolutely insane with anxiety as though this one evaluation determines my whole life. Perhaps it does, but I'll never know till I soldier my way through it. Let's hope I don't kill my stage pilot!
