A complete guide to UPSC Civil Services Examination: eligibility, exam pattern, syllabus, preparation strategy, and frequently asked questions.
About This Exam
The UPSC Civil Services Examination is the most prestigious and competitive government exam in India, attracting around 10 lakh applicants annually for approximately 1,000 final selections across the IAS, IPS, IFS, and 24 other central services. The success rate of less than 0.2 percent makes it one of the toughest exams in the world. Candidates spend one to three years in serious preparation covering an enormous syllabus that ranges from ancient Indian history and constitutional polity to economics, geography, environment, science and technology, and contemporary international relations. The exam tests not just your knowledge but your ability to write coherently under pressure and articulate balanced views on complex issues during the Personality Test. Selected candidates undergo training at the Lal Bahadur Shastri National Academy of Administration in Mussoorie before being posted to their assigned cadres. The IAS in particular offers the rare combination of administrative authority, policy influence, and lifelong stability that few other careers in India can match. UPSC accepts graduates from any discipline, and successful candidates have come from engineering, medicine, arts, and commerce backgrounds alike.
