Hi, I had used Saunders, Lippincott, and the NCLEX 3000 CD. I felt that the books were beneficial because I could take them with me and study if I had a moment or find a comfortable place to review. The CDs were good because I could take practice tests and see what the rationales were immediately after answering the question. I found that method of studyng (paying attention to rationales) to be most helpful. The CD ROM also allowed me to practice what it was like to test on the computer. I felt prepared for the test when I went in, but once I came out I was so unsure of everything (as is the response from most test-takers). There was a class my school offered that reviewed systems and went over test-taking strategies. It lasted the entire last semester and we had to do anywhere between 100-200 questions per week over 14 weeks time in addition to our regular studying. Research shows hat those who practice at least 3000 quetions or so have higher chances of passing the NCLEX. Some people say they underestimated the test, so it may be helpful to over do it with the studying so you go in ready to do your best.
My test covered all areas (Peds, Maternity, Geriatric) and all topics (Neuro, Endocrine, etc). I feel like studying insulin and other endocrine issues was beneficial. Also, really focus on questions that deal with prioritizing patients and recognizing what should be done first in emergent situations. Really, you can get any kind of question on any topic, but those were some areas that were helpful in my preparation.
I hope this helps. I can send you the Lippincott book in case you're interested and I think I have the NCLEX 3000 CD here as well...anything to help a fellow nurse. Best wishes.
