Here is my story and I hope it helps.
The first time I took the NCLEX I failed at 265 questions. I prepared by using Kaplan online classroom and the q-bank study questions. I averaged around the high 50's and low 60's. I wanted to reschedule the test but didn't listen to my inner voice and went ahead with it anyway. I thought to myself, I was an A/B student in nursing school
, just graduated so I am sure I will pass this test. (Also let me add...I also had a lot of personal issues going on in my life like a bad bf, new house, etc). When I failed I was miserable and devastated. I took about a week to lick my wounds. So I dusted off the bruises of defeat and reevaluated where I went wrong.
Second time I took the NCLEX I passed at around 80 questions. I purchased UWORLD, LaCharity and and studied even more lab values. I did every single chapter in LaCharity AND read the rationale. I can not stress enough how important it is to read the rationale so you can have a complete understanding of the question. If you don't have the content down, you are not going to be able to approach an NCLEX question with your guns loaded. Also, the weeks leading up to the second time I tested I exercised and ate brain power foods like lots of blueberries, salmon and walnuts. And get plenty of H20 and rest the week before you retake. The days leading up to the test treat yourself to something you like to help you relax. I got a mani/pedi and went shopping the weekend before. The day before the exam I studied for about one hour in the morning and then I closed the books for good.
If you get a solid foundation on the content area and keep yourself relaxed and well nourished/hydrated you will have a better chance of staying focused and absorbing what you need.
I hope this was helpful and wish you all the best. Lick your wounds over the weekend then get up and dust yourself off. You can do this, you made it through nursing school for a reason. Best of luck!
