I took the NCSBN learning extension 3 week course and highly recommend it to anyone preparing for the NCLEX RN and especially to anyone who has taken the NCLEX and failed. I failed three times. I was not going to take it again, but eventually decided to try one last time. I have three kids so it made it hard to study. I did not even make it through all of the content because I would get overwhelmed and discouraged. I took the pretest, the postest, and did all of the practice quizzes. DO ALL OF THE PRACTICE QUIZZES AND READ EACH AND EVERY RATIONALE FOR EVERY QUESTION, EVEN IF YOU GET THE QUESTIONS RIGHT. If you have time do the quizzes over and over again. Not only is the content right on for the NCLEX RN, but these questions will help prepare you for the way the questions are worded on the actual exam and the NCSBN learning extension is always up to date to the current test plan. I was on the website for 1-2 hours a day everyday for three weeks. Thats it. I did the NCSBN learning extension and flash cards of lab values that I had made myself. Do the quizzes, read the rationales, and know your lab values and you too will be on your way to being an RN! Best of luck!!!
