Officials declined to provide copies of the test, which was a multiple-choice exam.
The incident has cast a spotlight on the education sector in this West African nation still recovering from a brutal 14-year civil war that ended in 2003.
Along with the undergraduate applicants, all candidates for graduate programs in law, pharmaceutical studies and six other graduate programs also failed, according to a university press statement.
After the dismal results were in, Liberia President Ellen Johnson Sirleaf laid out a plan Wednesday to relax admission standards to enroll 1,626 undergraduate students as well as a handful of students in each graduate program. She said the test results underscored the need for further reforms.
"We concentrated in the early years on enrollment because we wanted to get all these young kids into schools," Sirleaf said. "We wanted to get them out of the farms, out of the markets, out of the street selling, and we did that. Enrollment has quadrupled since we started."
The next step, Sirleaf said, is improving education quality.
"That's the most difficult task. You got thousands of teachers in our school system, some of them with only a high school education," she said. "You don't turn that over in three years or four years or five years."
Not everyone agrees with Sirleaf's analysis. The university spokesman suggested the students might be to blame.
"Perhaps they didn't study, because our students don't like to study," he said. "Liberia itself, it's not a reading public. Go around and ask the people in the street, 'Did you read a newspaper yesterday?' They will say no . That culture of not reading, if you bring it to college you're going to fail."
Getaweh acknowledged there had been some problems in administering the test in previous years. He said that up until last year, the official in charge of testing used "statistical analysis" to determine how many students would be admitted on a curve. The exact formula was a mystery to every other official at the university, Getaweh said, but the system went unquestioned until last year, when 7,800 students were admitted more than double the previous average total.
When top university officials went to the official, he refused to explain his methods or provide raw scores, leading to his suspension.
Prince Camara, 23, said Liberia's education needed an overhaul whether the exam results were credible or not.
"We hear on the radio that the future of this nation lies in the hand of the youth," he said. "But our leaders, they are not willing to give us quality education to see how best we can lift our country up higher."
