I think you can talk to your College Dean or any members of the faculty of nursing in your own school. They may have access to some official stack ranking from PRC of some sort. I don't know how and where other schools got it but during the time our board exam result came out, I learned that I was top 18 through my workmate. Her school posted her and many of her other schoolmates's name in the broad sheet newspaper. She was top 22 and since she knew my board rating she told me I was top 18 by just comparing our ratings. There was 0.20 difference per rank in my batch.
I really envied her then since her school posted the top 25 examinees. My own school didn't. They were just focused on the 5th and 8th placer examinees who came from our school that time, oh by the way I am not in any way bitter about it at all, but it would have made me feel better if my name was posted alongside our topnotchers since we almost made it to the top ten ahahaha.
2 years later, on one of my visits to PRC to get a copy of my board rating, I asked in one of the windows if they can provide me an official copy of my ranking...I was under the impression that they provide that because I've seen some action slips which are specific to the ranking but I was told that they are only doing it for those who belong to the top 10.
Yay, too bad...haha I think people like me wouldn't have anything official to hold on to in proving how we guys almost made it to the top 10. I guess I'd just rather brag about it specially during interviews or when asked about my rating. Haha. Not all applicants get that kind of rating anyways so I'm content and proud of my achievements whether it is official or not.
Hmmm one last thing, if you guys graduated from Arellano University and Baliaug State University, there's a higher chance that your name will be posted in any official publications (newspapers or websites) if you belong to the 11th-25th board placer bracket. The friend I was referring to above was from Arellano University.
