UPSC CSE Prelims 2026 Exam Pattern

UPSC CSE Prelims 2026 is the first stage of the Civil Services Examination and is conducted as an objective-type screening test. The Prelims consists of two compulsory papers: General Studies Paper I and General Studies Paper II, also known as CSAT. Each paper carries 200 marks and has a duration of 2 hours. The total marks for Prelims are 400, but these marks are not counted in the final merit list; they are used only to shortlist candidates for the Mains Examination. CSAT is qualifying in nature, and candidates must score at least 33% in Paper II. There is a negative marking of one-third of the marks assigned to a question for every wrong answer.

UPSC CSE Prelims 2026 is balanced but challenging. Candidates should focus on high-weightage areas such as Economy, Polity, Geography, Environment, Science & Technology, History, and Current Affairs. For CSAT, daily practice of comprehension, reasoning, and basic mathematics helps candidates clear the qualifying cutoff. A smart preparation strategy, revision of static topics, and integration of current affairs are essential for better performance in the exam.
