I took the NCLEX on 3/13 and passed! My test stopped at 75 questions and I was pretty sure I failed. I literally guessed at every single answer on that test. It was very difficult. Way different than the prep questions I had done. I had a lot of med questions and they were all meds that I had very little knowledge about. Definitely not common meds. Also had a lot of select all that apply. Anyway, just thought I would share how I prepared.
Our school required that we purchase the ATI program. It is a fairly decent program for preparing you for nclex. I went to the prep class ATI offered and then I just did the practice questions. I did every problem they offered and then I did them again. I guess about 1000-1500 questions total. I also had the ATI app on my phone and I would do questions on that all semester long when I was bored or waiting at a doc appt. or something. I do think that also helped.
Make sure when you do the questions, you read the rationales. It's really important and probably the best way to learn the information.
The day before the test, do not study! Just relax and try to get a good nights sleep.
