Accepted By Voicemail?

My son applied to AU on Oct 5. The AU admission office called and left him a voicemail this afternoon. He missed the call because he was at wrestling practice. It was to congratulate him and inform him that he got accepted to AU. They said that he should receive the official acceptance letter in the mail later this month. It was nice of them to call the students and let them know that they got in.

His stats = GPA 89, ACT 26, Varsity wrestler (5 yrs), few HS clubs and volunteer work.
