ok, in the anime and manga it says that naruto failed the genin exam many times (cannot remember exact amount atm, i think it was like twice) now what i want to know is howcome the other students of the ninja academy, like sasuke or sakura, didn't move on to become a genin while naruto stayed in the academy? did they attempt to become a genin later than naruto or something. because if they didn't and giving that we know that naruto got "kept down" then they should have moved on while naruto stayed in the academy.
so what is the deal with this? did naruto start a few "grades" earlier than sasuke etc.
ok thanks
