You think she'd have anxiety, like us? Oh god, like us... xDDDDD It's not possible. The need for an increase in rank wouldn't be as important as becoming stronger with a Legendary Sannin. He can always take the exam later on and absolutely crush it later. For now, Sakura and Ino can be the stars, as well as EVERYONE ELSE who became Chuunin over the two and a half year timeskip. Let me just say that if we get far enough, IF we get to the point Naruto comes back, he's going to be a lot more grown up, and a lot less naive.
