The decision of selection of the optional paper for IAS exam is an age old dilemma for Civil Services aspirants. As per the latest syllabus, the number of optional subjects to be selected is reduced to one, but aspirants are still confused if they make right choice or not. Though the weigtage of the optional paper is only 500 marks out of 2025 marks as per the latest pattern of UPSC Civil Services exam, it is still a deciding factor in the final ranks due to the unpredictability associated with General Studies Papers (1000 marks GS + 250 marks essay) and Interview (275 marks).
