7/18/16--Pearson VUE trick accuracy?

Hey all! I took the NCLEX today at 2pm and it shut off at 75 Qs after about 45 minutes. I honestly can't say if it went well or not; I found that I was mostly giving my best guesses for the majority of the exam and the topics/questions seemed pretty obscure. I had maybe 20 SATA, 2 EKGs, a drag&order, and 2 exhibits. I obviously walked out feeling like I must have failed because I didn't feel confident about so many of my answers...

Anyway, when I got home, I tried the Pearson VUE trick and got the "good" pop up (Our records indicate that you have recently scheduled this exam. Another registration cannot be made at this time). 2 hours had passed since my exam, and I tried it again an hour later and got the same message. How accurate is this trick?

*I've heard of people trying it and getting the "bad" result, yet still passing in the end. But I've never heard of anyone getting the "good" pop up and then failing in the end, so can I mostly rest easy here? Trying to gauge!!
