The marking scheme for the UPSC Main Examination consists of a total of 1750 marks. Each of the nine papers carries different weightages, with subjects like General Studies, Optional Subjects, and Essay being integral components. Within this structure, candidates are graded based on the quality and depth of their responses. There are penalties for incorrect answers in the preliminary exam, but in the mains, marks reflect the candidates' analytical skills, articulation, and adherence to the expected format. This strategy aids the UPSC in identifying individuals with sound conceptual clarity and strong writing abilities.
