Frequently Asked Questions

How many IAS officers are selected each year? UPSC selects 900–1,200 candidates for all services combined. Of these, typically 80–100 get IAS, 150–200 get IPS, 30–50 get IFS. Total selection depends on vacancies announced.

Is it possible to crack UPSC CSE in 1 year? For a highly motivated, disciplined candidate with strong foundational knowledge: yes. But the average for successful candidates is 2–3 attempts. First-time clearance in 1 year is exceptional but not impossible.

Should I leave my job to prepare for UPSC? Many candidates clear UPSC while employed, studying 4–6 hours daily. If your job allows for this and provides financial security — don't quit immediately. Quit when you're ready for final 4–6 months of intensive preparation.

Which optional subject should I choose? Choose based on: Your academic background (your graduation subject is often a good choice), genuine interest, and overlap with GS syllabus. PSIR and Sociology have the most coaching support. Mathematics/Science optionals suit specific profiles. Don't choose based on "scoring" — it's your interest and effort that determines score.

Is Hindi medium viable for UPSC CSE? Yes — UPSC is fully bilingual. Hindi medium candidates appear and succeed in large numbers. All papers can be answered in Hindi. However, CSAT comprehension passages are in English (but can be answered in Hindi).
