I am very happy with my purchase and enjoy these lessons, looking forward to each new lesson every day. So far, I have learned more useful phrases (properly) in these five lessons than over six years of school lunchtime social immersion (plus weekends) with my Chinese friends back in school (although they taught me naughty phrases I will never learn in any course! :) ). I am looking forward to doing the rest of the course and surprising my friends with my new skills, and finally being able to have a bit more interaction with their lovely parents who don't speak any English. Very exciting!
