Query: Worst Textbook ever

This textbook is so terribly written. I'm currently using it in my honors biology class. The whole class is getting bad scores on the tests. It's written at a college level, and the authors expect that you have knowledge of every thing covered in the book. I don't understand why almost every 9th grade honors biology class uses this book. It made me lose all interest in Biology. I see kids crying in class when they get their test back, I sometimes cry as I try to study for this terrible excuse of a textbook. ALL the sentences are in a random order and have no correlation between them. You cant tell chapter 1 from chapter eight. Its all the same random words put together for "gifted students". If you can, don't ever get this book. If you are forced too, get ready for a long school year.
