Shocking
kumon was invented in japan by a man who had a son and he had problems with maths so he gave him a booklet to answer and he somehow spread it world wide. he written the booklets by hand at first just for his son!
Math in the 6th grade is the first level of a video game. It's challenging, but after a few more levels, you realize how easy it was.
It is. And remains so at higher levels as well.
About 2 to 3 years.
Toru Kumon invented Kumon. His son was having difficulty with maths at school. To help his son he made up Kumon. Soon he was good at maths. All the parents asked him how he was so good. Now there is Kumon all over the world.

Math is the foundation of engineering. Kumon helps with that. At the Kumon center I work at, I find that students who start early tend to be very quick and precise with their mechanics. More often than not students are at least a year ahead of their grade.
Kumon Learning Centers, and the Kumon method they teach, are named for their creator, Toru Kumon.
