1) Saunder's Comprehensive Review for the NCLEX-RN Examination
by Silvestri - This book is a great content review. I read it cover to cover during nursing school to prepare for the NCLEX and study for tests in school. There is a new 6th edition out, but the 5th edition is just fine.
2) Prioritization, Delegation, and Assignment: Practice Exercises for the NCLEX Examination
by LaCharity, Kumagai, and Bartz. This book is a must have. I went through 80% of the book. You must read the rationales to gain the full benefit. It also helps you with content through the different scenarios. The 3rd edition is coming out soon, but the 2nd edition is perfect.
3) Kaplan NCLEX Review http://www.kaptest.com/NCLEX/Home/index.html
- At the very least sign up for their qtrainer and qbank. The classroom prep teaches you how to answer questions. Taking the Kaplan course was the best thing for me because it taught me how to read and answer the NCLEX style questions and increased my confidence as I saw my scores going up on the qtrainers and qbank. I took the classroom course, did all the qtrainers, and answered ~80% of the qbank.
