Happiness quickly turned into despair last weekend when 67 students were mistakenly told they got into Vassar College, thanks to a computer-related error.

According a New York Times article, a "test letter" meant to be a placeholder for a student's actual notice of rejection or admission was never replaced, leading dozens of applicants to see a false acceptance status when they logged into the college's site.

Mistakes like Vassar's actually are common. Almost every year, at least one college erroneously sends that happy letter of "congratulations" to the wrong group of people. Apologies are usually immediate, but the emotional damage is already done.

Above is a slideshow of five schools that let down hopeful high schoolers enduring an already stressful admissions process.
