My son has a Cambridge English Class after school in his own school every Friday .I am lazy mom, we joined it mostly because it's convenient.
But lucky, he likes the teacher and the course very much, then we arragne he read small English books every day, now he reads PM+
His teacher had recommend us to learn OM, we are still thinking when and where to learn? At the same time, i bought an OM text book, his fasther often play it with him on weekend! We hope he can like OM..
