Hi, I cannot really tell, as we cannot speak for PMI/Pearson VUE.
Nevertheless, while I fully understand the enthusiasm and excitement when the "Congratulations" message appears on the screen (I went through it myself!), please notice that Pearson VUE recommends that "After completing the exam and answering the optional survey questions, you must fully close the application before leaving the view of the webcam." This is the only way to be sure nothing will go wrong
after completing your exam.
As for the results, it may take up to 3 days for PMI to update your profile on its website, and I spent an entire day wondering if I just dreamed I passed the PMP exam

Now I can tell you: you will get an e-mail notification from PMI eventually!
