HELLO, I RECENTLY TOOK NCLEX PN AND PASSED. SOME STUDYING MATERIALS I USED WERE SAUNDERS NCLEX COMPREHENSIVE REVIEW I I READ EACH CH. AND DID THE QUESTIONS AT THE END OF EACH SECTION, I ALSO PURCHASED EXAM CRAM PN 3RD EDITION, I FOUND THESE QUESTIONS WERE MORE DIFFICULT BUT IT IS GREAT FOR LEARNING CONTENT. There are five practice exams (200 questions each) i would break it down and do 100 questions at a time and than get my percentage, I was scoring btw 60-67%. If you need more questions like I felt I did, I also purchased Lipincott's 9th Edition for NCLEX PN and registered online and did all the questions per section. There are 2 comprehensive exams and I was scoring above 70%, this gave me the confidence, after doing about 6k questions to sit for my boards, it paid off, I passed. I studied M-F btw 4-6 hours with minimal breaks for bathroom and snacks, no cell distraction. Doing questions helped me a lot, you can do it, dedicate yourself and good luck, you can do this!!
