UGA officials say the admissions office accidentally sent out the congratulatory letter to the high school students who were supposed to receive a notice thanking them for applying, not congratulating them on getting in.
"Basically, someone picked up the wrong file and sent the wrong letter," UGA spokesman Tom Jackson told the Atlanta Journal-Constitution. "It was a mistake, and we are very, very sorry."
The university has since sent out letters of explanation and apology.
Natalia Prada-Rey, 17, was one of those whose excitement was deflated.
"They handed me my future and then, it's gone," she told the newspaper.
