I took the Nclex twice, one in July 2017 (81qs) and the second one just a few days ago (265qs). I got questions ranging from all of the different topics like growth and development, meds, procedures, lab values, infection control, ekg etc. Pretty much a little bit of everything.
I used Kaplan, but only the book that had the strategies, review and 265 practice questions which I just borrowed from my local library. I read the entire strategies and review, then after that I answered the questions probably 10-20 at a time, then I would read through the rationales and write down the important things that I can just go over again. So that is what i did for all 265, i pretty much finished that after 5 days. I also used the Lacharity book for the prioritizations and delegations, this really helped me in my exam because all throughout my exam the second time around I had a lot of prioritizations. I also borrowed this book from my local library. I didn't get to finish through it since I couldn't renew it again since someone else had reserved it. So after that, I purchased Uworld (1month subcription) three weeks prior to my scheduled exam. When I took my first assesment I recieved a high chance of passing. I did 75 questions a day in tutorial mode. I would thoroughly read the rationales before I go into answering the next question. And pretty much i think that is the most important thing which is really understanding why the answer is the way they are. Because when you read through that rationale, you will get another question that is somewhat similar to that topic and you can apply that little bit of knowledge to answer that one question. The scores on Uworld really doesn't matter, what matter is that you understand those questions and answers after reading through the explanations. When I took my second try on the exam last Jan. 9th, I received questions that were similar to the ones in uworld but just reworded in a different way or was approached differently, however the overall content of the question was the same. And i was able to answer it because I knew the rationales for the choices of answers that were given.
Best of luck to you when you take it again! :)
