Pros:<br>1) Many examples: The author goes through trivial examples first and then he gradually increases the difficulty.<br>2) Many problems: You will find many interesting and non-trivial problems here.<br>3) Some explanations are as clear as it gets. Also, some of them are more intuitive than any other explanation you might find in other books.<br>4) Tries to blend the structure of a traditional textbook with the structure of a problems book. This is done in a very successful way, although you can find better traditional textbooks on Quantum Mechanics that go into more detail on some of the material by offering more extensive intuitive explanations. But this is expected because those books are focused on only one approach.<br><br>Cons:<br>1) Some explanations are not so clear (although there are only very few of them) and some lack intuition (again, very few).<br>2) The aforementioned blending of two approaches means that a student will have an all-round better understanding of Quantum Mechanics but the reader will miss out of some details that could really deepen one's understanding. As I said, this is expected because a book cannot fully cover both approaches.<br>3) Although there is a huge selection of problems (and many are great), there are no answers on the back of the book. So, a reader who feels uncertain about his/her understanding of the material covered in a particular section, might not even know if he/she is doing something wrong in the exercises. That being said, there are many exercises that are proofs of something, so the above discussion is not applicable to these types of exercises.<br><br>In conclusion, even though I mentioned three negative points of the book, they are still not enough to overshadow the effect that the pros have. A great book.
