For a child to be successful in life, we must build the foundation while they are still young. A child must do well in academically at the same time he should have the ingenuity when he grow up.
For the academic side, the two most important subjects I believe they should master or at least be good at are Math and English. If a parent can afford it, they could enroll them at Score for a private English or math tutors.
Today’s youth is tomorrow’s leaders!
