"The results of this test are similar to those of the previous years. That's why the results are beyond any doubt," Vice-Chancellor Md Akhtaruzzaman said after publishing the results on Sunday amid demonstration by several organisations of students.
In 2017-18 session, 7,566 out of 76,989 candidates or 9.82 percent passed the exam.
Several media reported that the English section of the question paper was leaked on the eve of the exam.
The number of candidates passing English has risen by 2,698 compared to last year's test.
Arts Faculty Acting Dean and 'Gha' Unit admission coordinator Professor Sadeka Halim also refuted the allegation of question leak.
"No one could provide any proof of the alleged question leak," she said.
She also alleged that 'question leak rumours' were spread to 'make the test questionable'.
Then VC Akhtaruzzaman came out and told the students that protesting against wrongdoings is good but breaking the lock is never a good thing to do.
He said detectives investigated the allegations brought by some media but found no truth in them.
Later after publishing the results, he alleged that an "evil group was behind the question leak rumours that aim to damage the university's reputation".
