I've heard horror stories of applicants turning in their apps with one score on file and waiting for another score to come in and the school not waiting for the second score. If you want to be safe, wait for that second score to come in.
Paige, what happened after in that story? Did the applicant re-apply after being rejected or was s/he able to pull out from waitlist pool by updating the score?
I have out right now part one of a series called The Imperfect Love. I also have an older short story available Tales of the Broken Hearted. They are available on Barnes and Nobles and Amazon
