Students who failed the HSC and equivalent exams staged a protest at the Dhaka Education Board, demanding the cancellation and re-evaluation of their results.
The demonstration, which began around 1pm on Sunday, escalated when protesters vandalized the office of the board chairman.
By 5:30pm, the protesters had blocked the Dhaka Education Board Chairman Professor Tapan Kumar Sarkar, along with other officials.
Professor Sarkar confirmed the incident, saying: "They vandalized my office, demanding an auto pass."
Despite the unrest, members of the police and army were deployed to control the situation.
Law enforcement officials were seen trying to calm the students and engage them in discussions.
The protest began earlier in the day, at 11am, with many guardians, including women, joining the students.
Around 2:30pm, the protesters forced their way into the board office by breaking the main gate's lock.
There were reports of violence during the protest, with six people, including three students, injured. Two of the injured — Priyanka, 18, and Jannatul, 18 — received treatment at Dhaka Medical College Hospital.
The results of the HSC-equivalent exam were released on October 15, but protesting students claim the published results were unfair. They are demanding the introduction of "subject mapping," based on the marks obtained in their SSC exams, to re-publish the results.
The controversy dates back to the postponement of several exam dates due to the quota reform movement in July and August. Subsequently, the Inter-Education Board revised the exam schedule, but many students demanded that the remaining exams be cancelled and their results be based on subject mapping instead of exams.
In total, 1,331,058 students appeared for the HSC exams this year, with 295,749 failing. Despite having passed individual subjects in the subject mapping process, these students failed the overall exam, leading to widespread discontent.
