First of all, Korean is a difficult language. No matter how good your book is, it is still a difficult language to learn, but a bad book doesn't help.... The introduction of this book mentions about a current trend in teaching new languages. Attention has shifted from teaching grammar and so on to actually doing something with the language which is not a bad idea. However, I'm a bit puzzled by the authors intentions. When trying to do the exercises I have found that most of the words you need to do the translations are not mentioned in the text before the exercises, so the student has the following options: a) browse through the lessons following the exercise, b) look up the words in the (not too extensive) wordlist in the back of the book c) read the key to the exercise and copy it, d) make a wild guess. Whichever option is chosen, I think the effect is far from optimal and, quite frankly, I find it highly annoying. Another point is grammar. It's not explained well and I'm sometimes confused by what seem to be inconsistencies in the dialogues and exercises. Fortunately, my significant other is Korean and she is a big help, but I don't think everybody has the luxury of having native speakers nearby to help you out. It has some good points though (which explains the two stars): Hangul (the Korean 'alphabet') is explained quite well and thoroughly and you can learn quite a few things about Korean when you work through this book. All in all, I think this book will teach you more than a phrasebook will ever teach you, but I think there are better books available (I wouldn't know which one, because I haven't looked at any other books).
