The Union Public Service Commission (UPSC) Civil Services Main Examination, commonly known as UPSC Mains, is the second stage of the Civil Services Examination. It is conducted after the Preliminary Examination and is designed to assess a candidate’s knowledge, understanding, analytical ability, writing skills and suitability for a career in public service.
Unlike the Preliminary Examination, which consists of objective-type questions, the UPSC Mains Examination is descriptive in nature. Candidates are required to write answers on a wide range of subjects, including history, geography, polity, economy, ethics, governance, science and technology, and international relations.
The UPSC Mains examination consists of nine papers, out of which seven papers are counted for merit ranking. The remaining two papers, English and one Indian language, are qualifying in nature.
The written examination carries 1,750 marks, while the Personality Test (Interview) carries 275 marks. Therefore, the total marks considered for the final merit list are 2,025.
