Civil services aspirants have been demanding the scrapping of Civil Services Aptitude Test (CSAT), calling it discriminatory for the students from humanities and Hindi backgrounds.
"We will continue our protest until we get a written assurance that the examination date will be extended and the CSAT exam will be scrapped," Anurag Chaturvedi, an aspirant, told IANS.
He added the students have wasted a lot of time because of the ongoing protests and cannot prepare for the August 20 examination in 25 days.
