Ok, lets ask. When you fail an exam for graduating, you're supposed to do the year again, right? So like u would be again in the same class and older then your classmates. And here comes the problem: Shouldn't Naruto be 3 years older than Sasuke, Sakura etc. if they passed on the 1st genin graduation exam and he failed for 3 times and repeated till Kage Bunshin?
