Typically, about 0.1% to 0.2% of candidates qualify for the UPSC mains exam from the prelims stage. Given the vast number of aspirants—often exceeding a million—the competition is extraordinarily high. Candidates must be well-prepared and possess a strong understanding of the syllabus, current affairs, and policy issues. This low qualification rate emphasizes the necessity for strategic preparation, time management, and effective study approaches. Success in advancing to the mains requires a deep commitment to comprehensive learning and mastery of required subjects.
