A Florida university accidentally sent out more than 400 acceptance letters for applications still under review.

The University of South Florida St. Petersburg sent out some 430 acceptance letters on Saturday to potential students that were quickly revoked, the Tampa Bay Times reported.

The applicants said their excitement died quickly after they received a follow-up email that day that stated: “There was an error in the system. Please disregard the previous email.”

Izaiah Harris, 17, a student at Pinellas Park High School, told the Tampa Bay Times he contacted the college after receiving the emails and was told there was an error in the system.

"I'm really confused and time is running out," Harris said. "This is throwing my plan off because there are decisions I need to make."

Samantha Santos, who also attends Pinellas Park High, said she was excited to learn she was accepted but became disappointed after receiving the second email.

“Getting the acceptance email fulfilled my dreams,” Santos told the Tampa Bay Times. “When I received the second email, it was like my dreams were crushed.”

Chancellor Martin Tadlock said “human error” caused 680 acceptance emails to be sent out when only 250 applicants were originally admitted.

University spokeswoman Carrie O’Brion said in a statement to Fox News that the school was "dismayed to learn about the acceptance emails."

"As soon as we found out about the situation, we immediately reviewed our process for communicating with prospective students and have changed our procedures to prevent this from happening again," the statement read. "In addition, our staff is calling each of the affected students to apologize and discuss their application status. They hope to contact all of the students by the end of this week.”
