I just had my Certification last October at MSNCB paper and pen. I didn't go for any review class or bought any review materials. I just used my old NCLEX-CDs and go through the concept -MED-SURG from Lippincott, Mosby, Saunders (old reviewers). Just study everynight after work if not tired and answered Q and A's at least 10 to 20 items because I find it so draining after work answering more than 20. If I'm off and in the mood, I would answer 50 to 100 Q and As. It's really worth, I was little cramming a night before the exam, I still studied a little, I slept late and got up early. Well, I was sleeply and so I did take energy drink to keep me awake and prayed. Just used some test taking strategies - elimination when I ddn't really know the answer. During the exam, I was very calm though. I reviewed those answers I was doubtful by placing a mark in the questionnaire that I have to go back. 4 hour-exam. Whew! I'm not a paper and pen test-taker because I lose patience easily but I made it. Just believe in yourself and pray of course.
