Query: This book needs proofreading

You would think that a book specializing in a subject that requires precise attention to detail - proofreading - would actually have been proofread! In the answer section they have failed to notice mistakes in their own text. Mistakes such as the spelling of the word "carrried" in exercise 50, and inconsistancy of hyphen usage between exercise 49 and 50. There are numerous other mistakes, and lack of explanation and examples in many other sections. Another important fact that is not mentioned in the book's description is that it is designed for use in high school. The fact is, this book is not even suitable for school use. It will leave a lot of teachers with shrugged shoulders and red faces. Very sloppy.
