Crack UPSC Prelims 2025 in Just 6 Months: A Foolproof Study Plan for Aspirants

The UPSC Civil Services Examination (CSE) Prelims is a gateway to one of India’s most prestigious career paths, and with the 2025 Prelims scheduled for May 25, 2025, aspirants starting now—on March 23, 2025—have exactly six months (approximately 180 days) to prepare. While the UPSC syllabus is vast and the competition fierce, cracking the Prelims in six months is entirely achievable with a disciplined, strategic, and focused approach. This foolproof study plan is tailored for aspirants aiming to clear the UPSC Prelims 2025, covering General Studies Paper I (GS) and Paper II (CSAT), with actionable steps, resource recommendations, and a month-by-month breakdown.

Understanding the UPSC Prelims 2025

The Prelims consists of two objective-type papers:

  1. General Studies Paper I (GS): 100 questions, 200 marks, tests knowledge of History, Geography, Polity, Economy, Environment, Science & Technology, and Current Affairs. Cutoffs typically range from 90-110 (out of 200), depending on difficulty.
  2. General Studies Paper II (CSAT): 80 questions, 200 marks, a qualifying paper requiring 33% (66 marks), assesses comprehension, reasoning, and basic numeracy.

With six months, or roughly 180 days, starting March 23, 2025, you have a tight but workable timeline. Success hinges on prioritizing high-yield topics, leveraging quality resources, and practicing extensively.
