I go there and it is amazing! You get close bonds with your classmates and earn lifelong friends from all around the world. There a different cultures and everybody respects them it's amazing! We have fun activities and the teachers are great! It is such a safe space. Sure your best friends move to some odd places that are really far away but then you go visit them and see so many new things. The teachers are the best in 3rd grade my teacher was able to teach the class times tables in 5 minutes! The homework is really good too. It started off in 3rd grade before it was just projects. But in 3rd grade it was easy then it got harder as we moved on. It is really the best school in the world. You or your children should totally go!
