I'm preparing to upgrade from CCNA to CCNP and I am looking for some insight into which Cisco Press books I should purchase. Each exam, except for CIT, seems to have a corrosponding Study Guide and Exam Certification Guide. Cisco recommends the Study Guide for those who are looking for in depth coverage of the topics. I don't have any formal CCNP training - I only have the knowledge required for CCNA. Should I go with the Study Guides, Certification Guides, or both? I would prefer to purchase the books in a bundle. However, since the CIT exam doesn't have a Study Guide, is it possible to buy the Study Guides in a bundle?
Thank you for your input,
