You're absolutely fucking retarded. To begin with very few countries have a similar system to that of Japan (if any at all, I don't know any) so there's no confusion here. I'm talking about Japan specifically.
Second, you're implying your source is shit you think you've seen in anime or someone has repeated here on /a/. You might as well make it up at that point.
>Mikan : 11 years shogakko 6th grade.
Yes. 6th grade 11/12. She hasn't had her birthday yet. She'll graduate elementary school as a 12yo.
>Illya / Kuro fate kaleid liner : 10 years shogakko 5th grade.
Yes. 5th grade 10/11. They haven't had their birthday yet. They'll advance to 6th grade as a 11yos.
>Miyashita mitsudomoe 6th grade : 11 years
See Mikan.
None of your examples even help your case nor contradict what I said.
Elementary schoolers graduate at 12yo and enter middle school about a month later. Middle schoolers graduate at 15yo and enter high school about a month later. Highschoolers graduate at 18yo.
Kuroko finished her elementary school as a 12yo and I have no idea if she has had her birthday yet, so she's either 12 or 13.
Mikoto finished her 1st year as a 13yo and had her birthday shortly after in May. The story takes place after May, so she's 14.
t. I've actually taught in Japanese elementary and middle schools before. Fucking idiot.
