Okay, so I posted this some time ago, but I didn't get the discussion I wanted, so... Yeah.
Student: omg omg omg omg omg omg guess what happened!!!
Teacher: *sigh* what now...
Student: okay, so I just passed my grade 8 exam!!! So that means that I can play anything in grade 8!!! Which means that if it's in grade 8, then I can play it! So in conclusion, I don't have to worry about whether or not something is playable for me. Which leads to my other statement that if I'm playing something and I don't know what grade it's in, then it doesn't matter. Which brings me to my next point that if I'm playing something in grade 8, then I don't have anything to worry about! All of this is because I just passed my grade 8 exam! If I failed, then I wouldn't be able to play anything in grade 8 because I wouldn't be good enough! So in essence, due to the fact that I pas-
Teacher: okay okay shut up!!!
Student: isn't that awesome?
Teacher: cool story bro, say it again...
Student: okay, so I just passed my grade 8 exam!!! So that means that I can play anyth-
Teacher: shut up!!! If you say another thing about this grade 8 exam again, I'm gonna wring your neck! Now hurry up and play this Rachmaninoff for me.

*playing some Rachmaninoff prelude*
Teacher: wow, you play this pretty well
Student: that's because I passed my grade 8 exam! If I didn't then I wouldn-
Teacher: GET OUT OF MY HOUSE!!!!!!!!!!!!!!!!!!

*later on that week, while looking for some new grade 8 pieces to play*
Student: wow I can't believe I passed grade 8! Hmmm I wonder what to play though, Prokofiev's second piano concerto, or Chopin's revolutionary etude? They're both grade 8, so neither of them should be a problem for me! I'll try Prokofiev's second piano concerto!
*next piano lesson*
Student: I'm going to learn this
*shows teacher the score for Prokofiev's second*
Teacher: you're joking... Right?
student: no, I'm serious!
I COULDN'T TELL WHICH ONE WAS HARDER BETWEEN REVOLUTIONRY ETUDE OR PROKOFIEV'S SECOND PIANO CONCERTO BECAUSE THEY'RE BOTH GRADE 8, SO I'LL JUST DIVE IN TO PROKOFIEV'S SECOND. Teacher: *there's no way he's gonna try this. Does he think he's cool or something?*: knock yourself out kid...
Idiot...Student: what?
Teacher: Oh, it's nothing... Just nothing...

*some considerable amount of time later in the hospital*
Doctor: well, it seems like you've shattered all of your fingers in 36 or more different places, fractured your skull, ripped out your tongue, broke all of your teeth, broke your nose, broke your face, broke both of your forearms in 29 places, dislocated your left wrist, Burnt your right wrist to the third degree, dislocated your hip into your spinal chord, blew up your right foot, broke three ribs so that they're now puncturing your heart, *deeeeeeep breath* AND you've somehow managed to contract every sexually transmitted disease known to man, the Ebola virus, bird flu, swine flu, osteomyelitis, osteoporosis, carpal tunnel, arthritis, elephantiasis in the hands, AND, aaaah forget it, I'm done. What were you doing anyway?
Student: I was practicing Prokofiev's piano concerto after I finished my grade 8 exam because I thought that it wouldn't be too hard because it's ranked as grade 8.
Doctor: WHAT?!?? Are you freaking crazy?! Of course this would happen to you!

. Well, I have good news and bad news: we can fix all of your illnesses... But I can't fix your fingers that are broken in 36 different places, or any piano playing related injury or disease so you can't play the piano anymore.
Student: NOOOOOOOOOOOOOOOOO!!! I feel soo salty!!!!!

Is this what Scriabin felt like after he damaged his hand? Or is this what Rachmaninoff felt when Tchaikovsky died? Why me?!?!?!?!?

Teacher: yes!!! I don't have to teach this idiot anymore!!! Whoho!!!
So in essence, I think this grading scale is stupid. Everything is rated an 8+! Are you kidding me?! How am I supposed to tell what's the difference between La Campanella and Rachmaninoff's third?! They should make a more sensitive scale! Like from 1-15? What do you guys have to say about this?!
