Losing my mind

I took the NCLEX-RN exam this morning at 8:00 and before I knew it the computer was shutting off. There are some questions I know I got wrong... I just stupidly picked the wrong answer. I had somewhere between 6-8 select all that apply questions, 3 calculations (one I'm pretty sure was wrong), and the rest is a blur. I remember looking at the # and seeing 72 then before I knew it the computer turned off. It must have been 75 because it didn't seem like many questions after the 72nd. I have mixed emotions about this exam. I walked out thinking it wasn't the worst test I've taken in my life... I actually felt kind of positive. Then I started to think that maybe I thought it didn't seem so bad because I was failing and easier questions kept coming my way. I've done many review questions.. all different sorts; Kaplan, ATI, Saunders, Lippincot (sp), the NSBN course's questions.. I did well over 3000. I just keep asking myself was it enough? I've talked with some folks I graduated with and so far 2 people have had all the questions and passed, 3 have had 75 and passed, one had all the questions and failed, and another had 75 and failed. I just don't know what to make of all this! Either I was rockin' this test or I failed miserably.
