This book was required for my university-level elementary japanese class. I really disliked it. I found it extremely unclear. The explanations for grammar were minimal and not nearly as extensive as they should have been for an english speaker trying to learn a language as unfamiliar as japanese. The book isn't engaging at all and actually made me lose my excitement for the language. It makes Japanese more of a struggle than it actually is. Don't but it if you don't have to.
