Query: Difficult to use

This book is NOT easy to read or follow. I found the layout of the book very cumbersome. I have used many different texts as I have homeschooled my daughter and this book is by far the most difficult to use. The instructions provided in WRTR for reading, writing and spelling are not at all well defined. It is not clear where to begin and where to end. I budget for my daughters school books every year and I now find myself having to invest in more books to cover these topics as well as putting us about 2 months behind schedule for this schoolyear. I found myself reading and re reading this book to try to make sense of it to no avail.
