Understanding the UPSC Examination Pattern
Preliminary Examination
The UPSC Preliminary examination serves as a screening test consisting of two objective-type papers: General Studies Paper-I (200 marks) and CSAT (Paper-II) (200 marks, qualifying with a 33% threshold). While Paper-I marks determine the merit cutoff, CSAT is strictly qualifying in nature.
Focus areas include Indian Polity, Modern Indian History, Geography, Economics, Environment, and Current Affairs. Our modules systematically break down NCERT concepts and standard references into structured notes tailored for Prelims.
Mains & Optional Subjects
The Mains examination is subjective and tests analytical ability through nine descriptive papers. Final merit ranking is determined by seven papers: Essay (250), GS-I to GS-IV (250 marks each), and two Optional Subject papers (250 marks each).
Neptunevines provides structured, analytical content for GS-I (History, Geography, Society), GS-II (Polity, Governance, IR), GS-III (Economy, Tech, Security), and GS-IV (Ethics) alongside expert guides for popular optional subjects.
