I just took the exam on March 9th. I found the verbal & math content to be painless. However my Chemistry & Physics skills proved to be rusty. I wanted to pace myself however I ran out of time on almost all of the sections. The worse part was NOT knowing if this exam PENALIZED you for GUESSING. At this point, I am still not sure if I would have been better off "rushing to fill in anything" during the last 2 minutes of the exam. If I can offer any advice PLEASE make sure you know that before you take the exam. I did use the Review Guide for RN Pre Entrance Exam, 2nd Edition by Mary E. McDonald and it was helpful. However, it cannot be your ONLY source for the Science content. Also, I found a FREE website that gives you 5000 SAT vocabulary words to study from. There were at least five words off of this list that I also saw on the NLN exam. http://www.freevocabulary.com. I graduated high school 16 years ago. Since then I have taken the SAT (for undergrad), the GRE (for grad school), the GMAT (for grad business school) & the LSAT (for law school) exams. Although they all were challenging exams, I found the NLN to be a little more challenging in the Chemistry & Physics sections. It was probably due to the fact that I havent visited that content since my first two years in college (14 years ago)! I guess I will find out my fate in another week or so. GOOD LUCK!!
