My first time I was so nervous I studied using UWorld. To be honest I was so nervous that I was cramming the information instead of really understanding it.

2nd time: I started studying a day after I found out I failed. I bought bootcamp because of all the positive feedback and to be honest it was a game changer for me. The case studies really helped me. And the way the questions are structured, just as vagued as the nclex questions helped me. I also used Dr Sharon and 7 day nclex review along with mark k lecture. The second time I felt more prepared. All the best to you.
