Which is better UWorld or Nclex mastery?
Consequently, is Uworld good for Nclex?
UWorld covers it all, don't kill yourself because doing UWORLD itself is enough work. You'll be good on test day, you'll be shocked at how much easier the NCLEX is. You definitely have had harder exams in your school/ATI tests than the NCLEX. You'll be good with UWORLD, do all the questions and rationales.
Correspondingly, how hard is Uworld compared to Nclex?
Yes, UWorld is more difficult than the NCLEX. I say that because the last 5 times I've taken the NCLEX, I got so many SATA questions that I had less difficulty answering them this time around, all because I did UWorld. The more questions you do and repeat, you will gain more confidence in how to correctly answer them.
Many nursing students make the mistake of preparing only for the minimum 75 questions. In your test exam prep, you must subject yourself to practice rounds with more than 75 questions. Otherwise, you may lack the mental fortitude to concentrate for the 6 hours the exam may last.
