I think you are going to be fine. However, make sure to do at least 90% of the question bank before your exam. I believe that helped me out so much!
My question trainer scores were not that great...I scored mainly in the 50s, some 60s. My readiness was 52%
THen, I got serious and started doing the question bank, really understanding the rationales for each question (right or wrong), and began to google topics I consistently got wrong, or used Saunders. I did not read a lot of Saunders. Maybe like 25% (or even less), just on areas I kept getting wrong over and over on Kaplan. My scores began to improve dramatically on the question bank. I was consistently scoring over 65+, and I got a few in the 70s and EVEN 80s! I was like WHAAAATTT! haha
I made sure to do as much question bank questions after I finished the trainers and also the 35pg study guide I found on all nurses, plus the nuclex cram sheet I found on google. I did those about 2-3 days before my exam. The day before, I just briefly went over the cram sheet again, but did not do any studying or read any new material or any questions for that matter.
The day of my exam, I ate a good breakfast, took some snacks with me to the test center (that I actually never got to eating). I passed in 75q! I thought the exam was SOOO similar to Kaplan, even a bit easier. I told myself after the first 100 questions I would go eat my snack and go use the restroom, but I never got to that point.
Best of luck to you on your exam! Remember to take each question one at a time! Don't read too much into it, and after you select your answer, go back, read the question and your answer choice again and make sure it makes sense. Sometimes, after reading the numerous choices over and over, it's easy to lose the topic of the question. This approach helped me out tremendously. Don't over-think and ask "what if." Do NOT change your answer what-so-ever unless you are 110% sure you misread the first time around. Your first answer is usually the right one! Good luck dear
