I just recently took my RN NCLEX exam on January 24th and tried the trick after 24 hours had passed and unfortunately it let me pay again so I thought I had failed but wasn't for sure. The next day (after 48 hrs) I paid for the quick results and did fail. Before I got my quick results, I spent hours on this site searching to see if the trick had really worked for those people who it DID let pay again and did not receive the "good pop up". So, long story short, this pearson vue trick DOES work. All my friends who it did not let pay again passed.
Good luck and let me know if you have any questions!
