For anyone freaking out because of all the people tha are coming here saying they failed, here's one that passed on their first try
I will be honest, I did not study very much. I did the Hurst live review, watched their videos online, and did two practice tests with 125 questions each, and that's about it. I did a 3 hour study session with a friend two days before I took my exam and the night before I looked over my normal lab values to make sure I knew them (I would really recommend this, it was helpful to know for the exam). I didn't spend weeks studying, I didn't do thousands of questions, and I passed in 40 minutes with 75 questions.
My biggest advice is test as soon as you can after graduating, I waited less than a month but in all honesty, I would have been ready just two weeks after graduation. The test itself I thought was a bit difficult (a lot of SATAs), and I wasn't sure I had passed as I felt like I was making a lot of educated guesses. But I got my RN license today, so even if you feel like you failed when you walk out, that doesn't mean anything! Good luck!
