Hundreds of students received false admission emails from Drexel University last week, according to the Associated Press.
Four hundred ninety-five high school seniors who were originally denied admission from Drexel or had submitted incomplete applications received a follow-up congratulatory email from Drexel three weeks later.
The email was to remind students of the reply deadline and was only supposed to be sent to admitted students, but was mistakenly sent to rejected students as well.
Drexel sent out another email to the students seven hours later, apologizing for the error.
Drexel made the same mistake in 1994, when it accidentally mailed admission letters to 25 students.
