Most of the aspirants end up underestimating CSAT, thinking that it has easy quant questions which can get them qualifying 66 marks out of 200. Hence, CSAT is kept as the last priority while preparing for UPSC CSE. This is a blunder. One must understand that if this paper is not qualified, the effort put in for GS and Optional papers will not be worthwhile. There have been many cases in the recent past where aspirants scored way above the Mains cut-off but failed to clear CSAT.
Therefore, CSAT needs attention, less time and attention than GS and Optional subjects, but enough focus and attention to qualify it with sufficient margin.
