Paul Yau, principal of HKCCCU Logos Academy, sent his sons to Kumon and saw good results, but cautions that extra tutorials may conflict with regular school programmes.
Mr Yau's sons, now in university, started with Kumon at a very young age and finished all primary school maths while they were still in kindergarten. The gifted pair were already doing calculus in Primary Six.
'My sons loved doing Kumon homework. During a visit to the United States, the first thing they wanted to do every time our car stopped, was to do Kumon maths,' he said.
He said Kumon was good for gifted students because it allowed them to speed ahead according to their ability. 'In school, you always have to follow the syllabus no matter how well you do.'
He said Kumon had sound teaching methods that were not as mysterious as people might think.
'Kumon has no magic - it can't turn poor maths students into mathematicians. But its materials are systematic and cover various types of topics and equations. It allows students to progress gradually through everyday practices. When you practice every day, it's only normal that you improve extensively,' he said.
