I found out today that I passed my NCLEX-RN exam and its all thanks to UWORLD!!!! I have used Kaplan, Lippincott, Hurst, Exam cram and none of these worked for me. In all of these reviews I did all the questions and even exceeded the scores that supposedly I needed to pass the nclex-RN and I still failed the NCLEX-RN on my 1st and 2nd attempt. A friend of mine told me about uworld and all I could say is, its way better than any other review in my opinion. I loved their rationals, format, and how it compares your scores to the average score that everyone else is receiving. The questions on uworld are way harder than Kaplan and mirror the nclex. On my 3rd attempt at the NCLEX-RN I felt like I was taking another test from UWORLD. All I used for my third attempt was uworld and nothing else, the rationals are very detailed so I didn't even have to look at my sanders book and it explained why the other questions are wrong. I have nothing but good things to say about UWORLD and would recommend it to anyone scheduled to take the nclex-rn!!!!!!
