There are many good study guides on the market to review. Motivation and interest in what you do are the key ! I've studied with "Saunders comprehensive review for NCLEX-RN" it comes with a free CDrom with 3500 practice questions, rationales and test taking strategies... and the money back guarantee if you do not pass ... I have studied and worked at the same time...so it is doable especially when you do not have the choice to do otherwise. Good luck !
