What I found helpful was practicing my skills over those subjects and having a friend from the class quiz me asking "why are we performing this skill?" and "what are you looking for?" Leaarning and studying while having tactile applications really helps to cement stuff in your mind. Also find a good study group, they don't have to be your soul means of studying but spending an hour or two a few days a week quizing each other and hashing stuff out can be beneficail. sometimes other students remeber things that you missed or you may be able to bring something to the table, but pick your group wisely, you need a group that will be benificial to you not detrimental. Oh and sometimes text books will offer NCLEX questions either at the end of each chapter or online with an access code, a lot of the time the questions can give you a feel of what you may see on the test. Good luck on your next exam!
