Of course, like many viewers pointed out, parents also play a critical role in improving their children's education.

As a father himself, Geoffrey believes in the importance of parental involvement. "It's not simply handing our children off to a school and saying, 'You educate my child, and meanwhile I don't have to pay any attention to this,'" he says.

It's also important for parents to understand the difference between homework and studying. "Your child does his homework, then that's done. Then, they still have to put time in studying so they're preparing," Geoffrey says. "That's why we're being beat by the rest of the world."
