The good pop up means you failed (that's why its called GOOD)..hee hee. Of course silly rabbit you passed. Welcome to the 2014 RN newbie Club
if you get a pop up that says something like, "Registration can not be done as test results are on hold," this means nothing, just that your test is being reviewed. This is neither good or bad.
If it says, 'Our records indicate that you have recently scheduled this exam,' and it won't let you schedule a new one, it likely means you passed.
If it goes to credit card details to let you pay, it likely means you didn't.
