This is so bad it's almost funny like have you ever wondered what the most useless way to try to teach someone a language is? It's this book.
It's specifically meant to be listened to, but you will pick up nothing listening to this. It says a sentence in english and then a sentence in korean and then immediately goes on to the next and the next and the next. No repeats, no slowing down, no chance to absorb a thing. It's just someone reading an english-korean dictionary to you without pause.
the other reviews are accurate, this kind of sucks as a resource - you could get the same thing (but much better) through podcasts and other audio sources like from TalkToMeInKorean
i just ended up using it for listening/writing practice
