first, since naruto and sasuke came out with 12, it would increase the chance of bolt/sarda also graduating with 12, simply because the author mostlikley makes some "comparisons" to the parents :)

second, sasuke and naruto are noticeable older, naruto looks like he easily reached 30 years, the same with the whole cast :D

thid, 5-11 is to short, the kids are intelligent but not genius's like the ones you mentiond, at least they dont give the feeling of "genius's" ^_^
