Obito has not graduated yet. He heard passers-by say that Kakashi is difficult to get along with, and then he remembered that Kakashi's personality changed a lot when they met last time.

The third generation arranged Minato to be Kakashi's tutor and told him about the death of Hatake Sakumo. Not long after, Obito graduated and joined Minato's team.
