The University of South Florida made a bit of an error last weekend after they sent out over 650 acceptance letters to potential students. The error happened because only 250 had actually been accepted while the rest were still under review.
As you can imagine, some of the students who received the first congratulations email were really excited to hear that they'll be going to the school of their choice. You can also imagine how disappointed they must have been once they received the second email explaining that they hadn't really be accepted yet.
Chancellor Martin Tadlock said "human error" was the culprit. The school is working to contact each applicant who received the erroneous acceptance letter to "discuss possible pathways" for future admission.
