We (my cohorts) were strongly encouraged to register with Pearson Vue at
www.pearsonvue.com/nclex to register and pay BEFORE we graduated. I went ahead and prepaid and got my little email reciept of payment from Pearson Vue but one cannot actually schedule an exam until you get your ATTfrom the BON. There are some additional instructions that should come with your ATT and on the Pearson Vue website about how to go about scheduling an exam date and time.
If you can, I'd go ahead an pay the 200 now--one less thing to worry about when the time comes.
Glad I could help.....Now if the BON will only send me my ATT.....
