I mainly use this book for the audio cd that comes with it and that has to be purchase separately. My sec. 4 ESL students, like it, the subjects are diversified but the level is pretty easy. Nevertheless, I was surprised at how difficult it was for them to get excellent results in the 3-4 sentences dictation. Therefore, I am still using it as a dictation tool. The other good point is that I always fin it difficult to get some relevant audio material where they can listen to native speakers. This one is helpful.
