So... I don't agree when Iruka says that Kakashi is the one who knows better the team 7 force. I think Iruka was right when he said that they were not ready for exam, because they're not!
1 They still don't know how to work in a team.
2 Sakura (i love her) at this point has a great potential, but cannot really fight-fight (kakashi basically didn't teach her anything, bah in general he didn't teach team7 anything... just climbing trees 😑)
3 Naruto and Sasuke keep fighting, and I feel like their rivalry, it's not the positive one that pushes one to improve the other, but just a kind of game between kids, or smt anyway not really positive (which, is for heaven's sake, pretty normal, how old are they at this point 13 maybe?)
So yeah, I'll forever stand with Iruka on this, he is right!
