The entire series is full overpriced rubbish designed to steal from children and incompetent adults. Richard, the owner of genkienglish(dot)com is a scam artist, and his trickery will catch up with him in time. Everything offered for an incredibly high price is available free online, and many of the serious English teachers in the world are seriously relishing the day when the British Council makes him pull his site down or return his passport because his behavior makes an international mockery of England.
