I just took a HESI in December that covered everything up to psych. I also just took the HESI last week for psych alone and did really well on both (91 & 90). My sister bought me Mosby's Review Cards for the NCLEX by Manno, which I did as much as possible. They really helped because it gave the rationale for every answer and they are separated into groups (Fundamentals, Peds, Maternity, Med-Surg, etc.) You might also want to check out NCLEX 3500 online; they had tons of good stuff there. The most important thing, however, is understanding the question thoroughly. Most sites will explain that NCLEX/HESI style questions are formatted in a strategical way. Make sure you read the question and reread it again to understand WHAT it's asking you. But, at the same time, don't "read into" the question. Weird, I know. We took the test on a computer and I asked for a piece of scrap paper so I could write down the number and A, B, C, D. As I did each question I put a line through the ones that were obviously not correct. Don't study the day of the exam (you'll get anxious and nervous). Make sure you get a good night sleep and eat a good meal before the test; you might want to bring a snack with you too. Just practice, practice, practice and remember your Airway, Breathing and Circulation! You'll do great. Good luck and keep us posted!
