I don't believe you can say that one particular kid is the smartest in the world. There are alot of mega intelligent kids who each excel in different areas. But it truly is amazing to see such a young black person slaying like this. Well done to him and his parents.
HOW? I'll never get how a six year old can be so smart, like how you gonna be 6 and in one of the best universities in the world?! When I was six I was just learning my times tables
What schools do these children go to
