UPSC Mains Syllabus 2025
The Civil Services Main Examination is designed to evaluate not just the factual knowledge or memory of a candidate, but their overall intellectual capabilities and depth of understanding.
The General Studies papers (Paper II to Paper V) aim to test the awareness and analytical ability of a well-informed individual. These papers are framed in a way that a person with a good general education and a keen interest in current affairs and public issues should be able to handle them without the need for specialized study. The questions focus on assessing a candidate’s grasp of key issues, their analytical thinking, and their ability to offer balanced perspectives on complex socio-economic challenges and conflicting objectives. Responses are expected to be relevant, thoughtful, and concise.
For the optional subject papers (Paper VI and Paper VII), the level of the syllabus is broadly aligned with an honours degree—more advanced than a standard bachelor’s level but not as extensive as a master’s degree. In technical subjects such as Engineering, Medical Science, and Law, the level corresponds to that of a graduate program.
The detailed syllabus for each of the papers in the Civil Services (Main) Examination is outlined below.
