I'm from PA and I just took the NCLEX the other week and I passed. I came home right away and got on the pearsonvue website and tried to re-register and I received a pop-up saying a test has already been scheduled. Therefore, the pearsonvue trick worked for me!
Another trick to find out the results of your test is to log on to the dept of the state website for the state you registered the NCLEX with, and look at the status of your license. I took the NCLEX on a Tuesday afternoon and logged on to the dept of the state website early Wednesday morning and found out I passed because it said license status: active and had my RN license number listed. Before I took the NCLEX, it said license status: pending. I would definitely recommend trying this first before paying $8 to pearsonvue and having to wait 48 hours for the quick results. I suppose every board of nursing is different for every state, but PA was super fast and had my results up less than 24 hours after I took the test and I didn't have to pay the $8 to pearson vue to find out!
