The protesters objected to the exclusion of foreign languages mainly Persian and Arabic from the list of optional subject for the mains examination.
A five-member delegation of JNUSU met a senior official of Department of Personnel and Training to register their protest.
"JNUSU is running a campaign for last one month against the recent changes in the UPSC syllabus and exam pattern - such as the exclusion of foreign languages as optional subjects in UPSC and the new CSAT pattern for preliminary exam," JNUSU President Akbar Chawdhary said.
"We are left with no choice and will mobilise youths to come on the road and march toward parliament in the beginning of winter," said Chawdhary.
JNUSU was joined by students from Delhi University and Jamia Millia Islamia in today's protest at Jantar Mantar here.
"The UPSC's decision of excluding languages such as Arabic, Persian, German, Spanish and Russian from its entrance exam is downright discriminatory.
"The same government which is speaking of globalisation is excluding these languages which are being taught in under graduate and post graduate and research level in several universities across the country," added Akbar.
