The marking scheme in the UPSC Mains examination allocates varied marks across different papers. Each General Studies paper carries 250 marks, with optional subjects typically having similar weight, while the essay carries 250 marks as well. Candidates must focus on clarity, coherence, and depth in their writing, as subjective evaluation predominates. Effective presentation of ideas and adherence to the prescribed word limit also impact scoring substantially. In addition, negative marking isn’t applicable in Mains, which emphasizes the importance of thorough preparation and quality of content over merely attempting more questions.
