I took it in June '05. I payed the $300 for the Kaplan review
online and studied all the books I could get, but I'm not so sure it helped. All my nsg instructors said that the NCLEX was going to 'multiple answer' questions - so they made all their tests that way (so we got adequate practice, they said)- but I only got 1 such question. Most of the 75 questions were 'priority' based - like you choose from 4 patients, deciding which one would be the most important to assess first. Another example: You are the charge nurse - which pt would you assign to the LPN, CNA, float nurse, ect. It wasn't like anything anyone said it would be, no one prepared me for those type of questions, but I passed!! I'm not sure, but I bet that the NCLEX people change the question 'types' every couple years - without warning.
The best advice I could give is don't get in a hurry and just really 'think' about the questions and answers. The right answer usually wasn't very obvious. Also, remember that they throw in questions that they are 'testing,' meaning they just want to know how many people will answer it correctly, but it doesn't count for you or against you.
My personal favorite study guide was the Lippincott NCLEX review and the CD that came with it - I especially liked the practice tests. Good luck!
