I was lucky to have other books and a great instructor in Quantum Mechanics, otherwise I wouldn't have learned the subject at all. The language of this book is very dry and abstract at the same time, leaving the reader without an idea of what it all has to do with the real life. The approach to teaching is by no means classical and lacks examples. Another thing that I didn't like (and that unfortunately occurs so often in scientific literature) is the way references were handled: the author would send you 10 chapters back to substitute formulas 178 and 186 into another one 5 chapters back to get a result on the current page, whereas in good books relevant formulas would just be re-typed once again for reader's convenience. Having said all that, I also need to say that the author did a good job picking the problems for this text. They are of moderate difficulty and well related to the discussion in a preceding chapter.
This is a good book, although it's hard to use, and the reason for that is simple: with such a great variety of problems in Quantum Mechanics it's next to impossible to conveniently systemize the content. I did find this book useful in preparation for my Ph.D. qualifying exam, but looking back I can tell that I would have passed without it. I think it's a great book for those looking for an easy way of doing homework, whereas educational value of this book is questionable.
