Or he doesn't even get that.
He said himself in the chuunin writing exam that it doesn't matter to him if he will be a genin forever and that he'll become Hokage anyhow.
He doesn't really care about being chuunin or jounin. His goal is to become hokage and before that to bring back Sasuke.
At the moment he doesn't really have something on his mind besides that.
And he would most likely gain nothing from it besides the title of chuunin.
He was of course a bit down at the time he heard he is the last gening from the group, but that was just for an instant.
Since then he has never even stated that he wants to become chuunin too (I think he didn't even say something like that at the time he got the news).
Not to mention that he is beyond that in terms of strenght
He'll either get promoted without an exam (which I highly doubt) or just stay genin until he is gaining the title of Hokage. You can pretty much count on that.
