I know what you are going through, it took me multiple attempts until I finally passed NCLEX-RN. My piece of advise is take your time studying, I took a whole year off and spent 3 hours a day studying. Not saying that you take a whole year off. Set a deadline so you know how to manage your time. Very important that you know that Pathophysiology of each disease. I write everything in index cards, that helped me. I also used LaCharity Prioritization Book. As much as possible don't study at home, go somewhere else like Barnes and Noble or maybe Starbucks, too many distractions at home. And maybe exercise to keep the blood flow to your brain.
