Possibility?????????

Is there a possibility that when u take ur test and pay to get ur results in 48 hours, you may get the wrong result?

I'm asking because I took my test on Sept. 23rd and paid to get my result in 48 hours on www.pearsonvue.com/nclex website; it said I failed. This is my second time taking the test and I remember the first time when I failed, I got a package within one week indicating my strong and weak areas. I still haven't received the package for the last test. I'm wondering if the pearsonvue website can sometime give wrong info especially saying that you FAILED.
