I purchased this book as a student hoping to learn more about Quantum Mechanics. Unfortunately, I was more confused about Quantum before I read this book than afterwards. It contains a number of typos, especially in equations, that are easy to spot with prior knowledge on the subject but will confuse the new reader. The writing is very dense, and can be difficult to understand. A strong understanding of linear algebra is also a requirement for understanding this book. This isn't a terrible book, but I won't recommend it and have found better resources simply by searching google for "quantum mechanics."
