Funny to think(dream) about it ...

Hi !! 

Let suppose you go one day to your lesson, and you tell your teacher "let me show you something, before we start"

And you play perfectly, at tempo and with great musicality, a piece that is COMPLETELY BEYOND YOUR LEVEL. 
For instance, for a beginner like me, it could be to play the complete Moonlight sonata  flawless, at performance level 

What do you think would be your teacher reaction? 

I can imagine myself being fired, accused of having cheated him about my piano level

If I were to go to my lesson and play something way beyond my level, it would probably be way beyond my teacher's level, as my teacher is *cough* not the world's best pianist. Therefore, my teacher would probably say "Very good!" and then change the subject as quickly as possible.

Sorta same here, I did that with Fantasie Impromptu and because she sorta thinks that she is much better than her students, she was like cool...ok....but now I practice that piece with her neways.

I only had 2 lessons with my teacher before I stopped, too much college work in the way :/ Can't wait to go back and bust out a good piece!
*Needs to perfect this prelude... and realises he has never perfected a piece*

You could fake your improvement over time... spend 3 weeks pretending to stumble on some Sonata she gives you, then the fourth week later, smash it out with perfect Clarity and all that yada!
I kinda wonder if my parents get tired of my music because they hear it constructed from the beginning, over and over it being played! If so, you would astonish her (or him I guess!) in this manner ^_^

That would be cool, but I think the problem is that perfect to the student is not perfect to the teacher...If I did that, I'm sure my teacher would point out that my articulations were uncharacteristic of the era, my voicing sagged in tonal energy, I failed to emphasize the important "deceptice cadence", and My interpretation was technically sound, but the "big Picture" was not cultivated...

and I've never done it since
