I'm sorry to hear about your not passing the NCLEX on the first try. Please don't let that discourage you from annihilating it on your 2nd and last try! You can do it!
I graduated with my BSN on June 26, 2017, from WGU and took my NCLEX July 13, 2017. Our school used the ATI RN Comprehensive Predictor and I scored with a 96% likely hood of passing NCLEX on the first try. I spent many daylight hours at the library. And I'm glad to say I have officially PASSED according to the Pearson Vue trick and the QuickResults! My computer stopped at 75 questions, but I was given the survey at the end of my test. I felt so bad that I didn't want to stay there anymore, but didn't get the test complete until the survey was complete! I hated every minute of the survey. The majority of my test was SATA and priority questions. About two weeks of intense studying. My first 3-4 days were spent doing the Hurst Review online that my school paid for. Hurst is great for content review, but be warned it's a crash course. Recommended study is 8 hours a day for 3 days. Be sure to print off the worksheets that come with Hurst. It's also good to have the completed worksheets to study the day or two before taking NCELX. Second, I used the Kaplan NCLEX-RN
Premier book and completed that book along with it's included online content in 3 days! I sort of liked this book because it had 2 practice tests with over 250 questions each along with access to an online NCELX simulator. Thirdly, I used the Saunders NCLEX-RN 7th edition and spent 4 days reviewing that book. The content in the Saunders book was very thorough and concise. Lastly, I used the ATI RN mentor app that's free and did TONS of practice questions the week leading up to my NCLEX test.
My advice which worked for me: STUDY and PRACTICE QUESTIONS!
I wish you the best of LUCK!
