I tested NCLEX-RN today (Mar-31st-2015) and completed around 2.00PM CST. I tried the trick after about 1 or 2 hours and its giving me good pop up "Our records indicate that you have recently scheduled this exam. Another registration cannot be made at this time." BTW: I did try my real credit card details as well as real credit card number with wrong expiry date and yes I tried all different credit cards and debit cards that I have like VISA, Master, AMEX, Discover and with all real info I always got GOOD POP UP....!!! So, I will keep everyone posted after checking again exactly after 24 hours and once I get my quick results as well as official results.... Keeping my fingers crossed and praying for the best to see my actual results in my hand..!!!
