As you all know, A expert(B.S. Baswan) committee was constituted by UPSC to examine and recommend any further changes in the pattern of Civil Services Exam, This was base on which students were speculating optional removal and CSAT merging into General sutudies paper. But now UPSC has given extension to that committee so this committee now has to submit report before 11th August, This means most probably no change will be done this year. Please keep preparing for your optional, This is most appropriate time for giving final touch to the optional, as later have to devote time to prelim.
