Kakashi, Rin and Obito

[Lagadatte]

So this might sound like a dumb question, but I was wondering, it is stated everywhere that Kakashi was some amazing genious, son of the White Fang and blablabla, graduated the academy at 6, became a chunin at 7 (holy shit, I could barely read at 7, Kishi's pushing it x.x) and then a jounin at 13, which is all very great! But! If he graduated the academy at 6 that means that he was assigned for training under a jounin, which in his case was Minato (who must have been what, 17?), but given that the regular age for graduating academy is 10-12 (even Minato the genious was 10), then that would mean that he SHOULD be assigned in a team with people older than him... so how come Rin and Obito are from his team as well? Were they exceptionally brilliant and graduated early too? (SOMEHOW Obito didn't leave such an impression... ) Or was the graduation age brought down, because of the 3rd Great Ninja War raging? Ideas?

(Sorry for the long post ;_; )

Not a long post and he could have been with other Jounin or Chunin at the time. Then could have met up with Obito and Rin later on.

Maybe he was a genius but he didn't have much field experiance so he had to group with the others untill a certain age

Obito and Rin could have been older then him.

Idk how he was a jonin at 13, they should've atleast shown him doin some great moves in kakashi gaiden but instead he just got saved by minato.
