first off, welcome to allnurses!!
i am just finishing the pn program. Once you get started, you'll be worried about the material for the test for the classes that you are in. Granted, when you are narrowing down to the last few months of school, the nclex starts floating back into your mind. Personally I bought one saunders review book a little after medsurg started to help with reviewing the material. And I brought a kaplan a month ago, I only have 3 weeks left of school and pinning. Throughout the program I would flip through the book and answer a few questions but rather then that, I havent started studying hard for it just because of all the other exams we have. You have to get through the program's exams to take the nclex. Good luck with school. Starting is the most exciting part.
