Hi, I hope you pass!
I took NCLEX on 6/14 and was cut off after 75 questions. The questions were tough and packed with clinical content. They were getting more and more difficult up until I reached the 60s, then they evened out.

Most were on prioritization of assessments/discharge, etc. 6-7 were "select all that apply", lots on pediatrics, lots on infection control/infectious diseases. I had no math questions, unfortunately, because it is easy for me... I think I was the only one who walked out of the exam feeling that I did OK (and I did - I passed!). Given that I am a book-smart nerd, my friends/family weren't surprised...
To prepare, I took Sally Lagerquist (Review for RNs; she is the editior of Davis NCLEX book) review and then studied and did practice questions ad nauseam. Additionally I purchased 3 weeks of NCLEX learning extention (learningext.com) tutorial, which was extremely helpful!!! It has lots of great practice questions and content review.
I had to take HESI back in February and scored very highly in it; it is supposed to be an acurate predictor of passing/failing NCLEX.
SOOOO glad it's over and now I am enjoying my last few weeks of freedom before I start my first REAL RN job in a big MSICU in San Francisco.
Good luck!
