Two years is a long time, considering he's a genius and also took performance enhancing drugs. Naruto improved nearly as much in the same time span so it's not too surprising. They were with the sannin for two years.
Edit: was it three years? I cant remember. If so then I really don't see the lack of understanding.

 

[LogicnoJutsu]

Because he was trained by a low-mid Kaye level shini I for 3 years, plus he's a genius

 

[Harsh srivastava]

he was quick to learn, had sharingan to learn, was with sannin , had cursed mark

 

[Dantee]

He's a genius and he's been training. What do you expect. My son is nice.

bro Sasuke raped Yamato, Sai, Naruto & Sakura and would of killed all 4 had Orochimaru not shown up with Kirin.

This is Captain Yamato the leader in this mission in the first confrontation with Sasuke, he could of easily been killed here
