Not necessarily, It seems that students are allowed to take the graduation every year, regardless of how many years they've been at the academy. If we assume that Naruto and Sasuke attended from ages 6 to 12, then Naruto's graduation attempts may have been biennial (once every two years), meaning that Naruto may have attempted to graduate during his 2nd, 4th and 6th years, finally succeeding on the last one.

Although it seems that the modern Academy is a whole lot more efficient and useful than some of the questionable subjects we know from the Naruto series (like flower picking). Agreed.
