But they refuse to take part in regular academic activities until the suspects are permanently expelled by the university.
The student protesters made the announcement at a media briefing on the BUET campus on Tuesday.
A representative of the protesters said the students will work in concert with teachers to stamp out criminal activities on the campus.
“Although we are calling off our protests for now, we will watch whether our demands are being met or not,” he said.
“And finally, we will not take part in any academic activities until those who are formally charged (with the Abrar murder) are permanently expelled by the university.”
Preparations for final exams are under way at Bangladesh's premier public engineering university after Durga Puja holidays. Term final exams are scheduled to start on Oct 19.
While announcing the suspension, the protesters had said they would resume demonstrations for their 10-point charter of demand after the tests.
Prime Minister Sheikh Hasina has criticised the demonstrators for pressing on with the agitation even after the authorities had met their demands.
Abrar was bludgeoned to death allegedly by a group of Bangladesh Chhatra League activists on the campus.
BUET has banned organisational politics on the campus and expelled temporarily the BCL activists accused of killing Abrar following protests.
The authorities later said in a notice the suspects would be expelled permanently following investigation.
It has also promised steps to stop ragging of freshers and torture in the residential halls.
The ruling Awami League’s student wing has expelled 12 leaders and activists over the incident.
Police have arrested 19 people so far and promised quick completion of the investigation to speed up the trial.
Hasina also said she ordered the authorities to take steps so that the trial is completed quickly.
