I am sorry that you failed the first time, do it again soon.
I took ANCC on September 1st and passed. I reviewed for 6 weeks, the first 4 weeks I did Hollier videos, Leik book, Leik App, Board Vitals, FNP Mastery and the APEA QBank. Then August 17 purchased Fitzgerald online, did it from August 17-31. I recommend Fits Non-clinical's but since I can not access the non-clinical part (last section of the lecture), I was forced to do the review from the very beginning, then was forced to follow Fitz "knowledge is power." I used the QBanks as a reward after each system. That 6 weeks of review include 3 days a week shift for 12 hours. I am just glad it is over. My advise, build on your knowledge, use Qbanks after each system. Do not rely fully on qBanks, it will bite you back. Once you know your material, whatever question you'll have you will be able to answer it. Prayer to calm my nerves also helped. I was so focused during the test, and was excited to submit "end of exam" and was telling my self, "I will walk out that door an NP," and it works. Goodluck.
