I felt exactly the same way with school. I JUST got by with my grades. We had our final exam less than a week before graduation and I was almost shocked that I passed, thus passing nursing school all together. I NEEDED that last passing 78-80 something to survive it. I was surprised when some other students (that seemed so confident in school and clinicals) didn't show up for graduation because they had failed the last test. There is so much pressure to not only pass school but also the NCLEX that it is completely unnerving. I don't know if you have a job yet but I had a graduate nurse job lined up right away after graduation. I knew that I wasn't ready for the NCLEX and needed a couple months to sort my brain out and absorb information from my new job. Once I got training and working with a nurse on my new unit everything that I learned in school clicked for me... the A&P, the labs, the meds, the actions taken in emergencies, all of it. The further I got from the text books during school (and cramming for tests) the more I understood because it was being applied in real life without the clinical instructor staring over my shoulder. I had a great nurse to help train me but I feel like the short bit of experience is what really helped me pass the NCLEX the first time. Don't get me wrong I still studied for my NCLEX like crazy after graduation but I found some questions that I got on my NCLEX were things that I had some sort of experience with on the tele/med surg unit that I was training on which gave me more confidence. I had 76 questions on my NCLEX before it turned off. I took my NCLEX in August. If there is any way for you to get that kind of real world experience before hand then I would try if your feeling unsure.
