Will CSAT be Removed from UPSC?

UPSC introduced CSAT in 2011 as a Paper 2 alongside the General Studies Paper 1. Soon after its introduction, CSAT quickly became a subject of controversy, sparking protests and concerns among aspirants. 

In response to the concerns raised by aspirants, the UPSC made some changes in 2015. From 2011 to 2014, merit was calculated by combining marks from both GS and CSAT. However, in 2015, CSAT was made qualifying in nature.
