I was feeling the same way as you two days before the test. I had a mild panic attack, and thought I should reschedule. I would say if you have been studying consistently with practice questions, you will do fine. To be honest, I would say 90% of the questions I got were NOT gone over in Nursing School or Kaplan. The NCLEX is designed to be a guessing game. To me, there is no amount of studying you can do to feel like you had a good experience at the end of the test. I cried at the end because I thought I failed. The main advice I'd like to offer, is do not stress out during the test like I did. Just take a deep breath, critically think, and eliminate answers. It's just a test, and if you don't pass..(only about 20% fail), so what? Doesn't mean you aren't going to be a great Nurse. It comforted me to know, if I had to take it a second time, the worst that could happen is that I would gain an even better knowledge base than I already have! Oh and keep praying- God will help you!
