Prof Kamrul Ahsan Chowdhury said he would take necessary steps on the basis of the recommendations of the committee.

"I will also call a meting of the academic committee of the department soon to resolve the problem," he added.

The chairman said the grading system had been implemented through a process and if it requires to cancel the system, then it will be done through a process.

Grading and semester systems were introduced last year only in sociology department of the social science and arts faculties.

Meanwhile, the first year students of sociology department continued their protest yesterday demanding immediate cancellation of the grading and semester systems.

They took out a procession and held a rally on the campus to realise their demand.

Addressing the rally at the foot of Aparajeo Bangla, the student leaders said they would never accept grading and semester systems.

They said the economics department also introduced the grading and semester systems but withdrew later on in the face of protests of the students.

"We will also resist the grading system with all our might and we will not return to the class until our demand is met fully", they added.

The students said as grading and semester systems have not been introduced at social science or arts faculties of any other universities, they will face problems in future.

"One can secure first class getting 60 per cent marks under the traditional system but under the grading system it will be Grade Point Average (GPA) D indicating poor result", they added.

The students of sociology department have been boycotting their classes since August 26 to press home their demands.

They have also threatened to go for hunger strike if their demands are not met.
