Protestors led by NSUI National Gen Secretary Mohit Sharma and Delhi State President Vikas Chhikara also raised slogans against UPSC and Central Government during the dharna.
"UPSC should immediately scrap CSAT for the welfare of Hindi-medium students. NSUI has decided to continue their protest till this test is scrapped," NSUI's national spokesperson Amrish Ranjan Pandey said.
Pandey said that the Central Government had promised the students that their demands would be looked into and nobody would be disadvantaged.
In the evening, activists called off their dharna after senior police officials intervened in the matter.
