The body that runs the Nigerian University entrance exam admits that this “technical failure” hurts some of the results of this year’s exam after nearly 80% of students have low grades.
Students complained that they could not log in to the computer, had no problems and power cuts, and were unable to take the exam.
The low pass rate has caused widespread anger, especially after a candidate took his own life.
Faith Opesusi Timileyin, 19, longs to study microbiology at university, and his family died after swallowing poison, her family said.
Her father and sister told the BBC that she took the exam for the second time, scoring 146 out of 400 points, down from 193 last year.
"The pain caused her to commit suicide," her father, Oluwafemi Opesusi, told the BBC Pidgin.
Typically, 200 or more of 400 people are enough to make the university a place in the university by the Joint Admissions and Admissions Committee (JAMB).

Fave Eke, a student, told BBC Igbo that 10 of 165 questions did not appear on the screen - all she could see was a multi-choice choice for the answers.

She also had technical problems and achieved results, which meant she was unlikely to go to college this year - she took the exam for the third time.
She took the exam in the capital Abuja, which was not one of the centers where students could retest, completely upset her.
Another student said it was difficult for him to log into the computer before someone else’s profile mysteriously appeared on the screen, showing different problems, and then the machine was completely shut down.
“I didn’t answer all the questions when they told us that our time had arrived because a lot of my time wasted due to these technical difficulties,” he said.
