User blog:Larry Berry/Wizarding World Schools?

Hi! Maybe I've missed something but every time I search the web for more infos, I got the same result. On Pottermore JK Rowling revealed that there are 11 schools in the Wizarding World. On Pottermore you can see even on the map they provided that only 7 are described. Hogwarts, Durmstrang, Beauxbatons, Castelobruxo, Uagadou, Mahotuokoro, Ilvermorny and Koldovstoretz. 3 are missing. What are they?

I'm interested in learning which school would you attend if you're from southern Europe, since all the school are in the north.
