I too failed my first try to pass nclex. I used Hurst and Kaplan. I utilized Hurst primarily; I completed the entire program. I did some Kaplan questions but didn't like and fully understand the rationales. I failed because I couldn't apply my learnings to the application, delegation and priority questions. I ran out of time at 233 questions and failed. On my second attempt, I utilized Uworld. Uworld has rationales that are broken down in a way that allowed me to truly learn more content and apply what I was learning. I finished the entire Uworld question bank with a 51% average. I read every rationale and redid every question I got wrong. Once I completed Uworld I went back to Kaplan questions. Surprisingly after finishing Uworld, Kaplan's questions and rationales made perfect sense. Kaplans questions were harder than Uworlds, but I was determined to use Kaplan too. I did about 800 qbank questions and rationales. I passed my second attempt with 185 questions and the questions were very similar to Kaplan's questions. I would highly recommend the approach of Uworld then Kaplan for anyone who is struggling with higher level nclex questions. I didn't do well asorbing all the reading and videos. I hope this helps you.
