Has anyone noticed alot of errors in the Osbourne BSCN study guide? I seem to find myself proofreading this book more than studying it. Questions with the wrong answers and the same question twice with 2 different answers: What are the 3 layers of a hierarchical network: my answer Core, Access and Distribution, book answer, Core and Distribution only for 1 question and later on the same question again and they say the answer is Core, Access and Distribution. It really frustrates me to rely on study materials if I cannot rely on the answers being right and having to check everything over. Some diagrams are missing IP adddresses and also in the answers they are putting in IP addresses that are not even on the diagram. Any recommendations as to a better book to get? Should I just go with the Cisco Press books? Thanks.
