Query: Students and newbies beware!

If I could put negative stars for this book I would.I am reading this book as a requirement for a network security course. This book by far has to be the most poorly written misleading book I've ever read. In the first chapter there is technically wrong information: The OSI reference model has a wrong layer numbered. I am surprised that colleges even bother to use it as a study guide\text book. The end of chapter questions are very misleading.
