Query: Need to hire an editor! The answers in the back are WRONG!

Hope you have an excellent teacher when using this book in class. In my case, Dr. Rotar, my teacher, makes this class a breeze. Higgins and Keller-Mc Naulty, the authors of this book really should have checked the answers in the back of the book before going to print.This book is horrible. The only reason I can understand anything is because my teacher corrects errors in the text.Loved the class, hated the book, steer clear of this one if you can!
