Hi there! I know you are frustrated, but a negative result is also a result! Do not give up - you can nail that Test! Now you have an advantage - you've been in that room, you know what to expect!
Now, as for orientation... Just reading books is not enough. Practice, practice, practice! You need to answer as many practice questions as possible and make sure that the percentage of correct answers is no less then 85! It will set your mind in an NCLEX mode. I only used 2 books: Saunders "Comprehensive Review for NCLEX-RN Test" and Saunders "Q&A Review for NCLEX-RN test". Both are the latest edition I could find. I did all the questions from Q&A book and CD plus I did some Kaplan questions (just questions, I didn't read any Kaplan's books) and couple of Kaplan's practice tests. Also I've found a link to online pharm book (someone posted here on this forum) and for the last week or two I was going through that book, answering questions after each chapter. That's all. Overall I went through 9,000 or 10,000 questions. I passed my NCLEX-RN on November 19th with 75 questions with the first try! I need to tell you that I've got my Nursing education in Ukraine in 1992, never went to Nursing school here in US, so if I could do this - you can do this too! Just believe, practice, make sure you do good while you are answering questions, leave all your worries outside of the test room and take all the time you need while taking the Test. Best of luck to you!!! In no time you will be an RN!
