I'm with Stephalump, love Saunders. I used an NCLEX prep book (I think it was also Saunders) during my LPN schooling. I would pop the disk in and formulate tests/quizzes specific to the info we were learning in lecture the night before the lecture. Honestly never really read the book for the class (i would skim it). I'd find out where I was weak with the test and be sure to concentrate on those areas in the book.
Currently I'm using Saunders 5th edition for my RN classes (last semester!) and I found by doing what I did in LPN school, I can find out where/what areas I'm weak in with the lecture material on focus more on that then the concepts I have grasped.
If your school is like the majority of schools
, gone of the days of simple multiple choice, fill in the blanks etc., now it will be NCLEX style tests. If you get used to that style ASAP its to your best interest. Any NCLEX prep book can give you examples of that type of question, but I much prefer Saunders than any other.
