Well, the reason nobody ever talks about the NCLEX is that you are supposedly forbidden to repeat anything you saw in the exam. (Did you ever see 'Fight Club'? ("The first rule about fight club is that you do not talk about fight club"!!). Anyway, Yes, I do think the exam was difficult, I do think you can learn it from books, there are loads of threads with info for good books. I did pass first time at 75 questions, but found the whole thing depressingly vague. I was hoping I would see questions where answers 1,2 and 3 would be obviously wrong for example, but it was just not like that. Many of the questions I could have agreed with say, 3 of the answers. So, in the end I just had to go with my gut feeling. There seemed to be plenty of prioritising questions. But then I think you just remember the questions you felt a bit shaky on. Good Luck by the way!!
