Only Mains + Interview marks count toward your final rank. Prelims is a screening filter — your Prelims score is discarded once you clear it.

Never fail CSAT
CSAT is qualifying only — but getting eliminated at 32% when you've studied for a year is catastrophic. Practice 4–5 past CSAT papers to ensure you never come close to the 33% threshold.
Optional is 500/1750 = 28.6%
Your optional subject alone is more than a quarter of all Mains merit marks. Combined with Essay (250), these two units are 750/1750. Choose your optional for scoring potential, not just interest.
Interview at 13.6% of total
275/2025 = 13.6%. A strong interview (200+) can compensate for an average Mains. Topper interviews typically score 170–210. See our Interview Prep guide for DM scenarios and opinion bank.
10% floor per paper
You must score at least 25 marks in each of the 7 merit papers (10% of 250). A near-zero in any single paper disqualifies you regardless of your aggregate. Never leave a paper unanswered.

EWS category introduced from 2025 CSE cycle. 2013–14 used a different marking scheme (higher absolute scores). 2023 saw the decade-low cutoff (Gen: 75.41) due to an unusually hard paper. All data from official UPSC cutoff PDFs. PwBD-1 = Blindness/Low Vision · PwBD-2 = Deaf/Hard of Hearing · PwBD-3 = Locomotor/Cerebral Palsy.
Safe score target
For General category: aim for 100+ to have a comfortable buffer. The 5-year average (2020–2025) is ~88. Attempting 75–80 questions with 70%+ accuracy is the standard safe strategy.
Never guess blindly
−⅔ per wrong answer means 3 wrong answers wipe out 2 right ones. At 80 attempts with 50% accuracy: net = 0. Selective elimination-based guessing is acceptable; pure guessing is self-defeating.
2023 anomaly
Gen cutoff fell to 75.41 — the lowest since negative marking was introduced. The paper had an unusual concentration of current affairs questions that wrong-footed even well-prepared aspirants.
Year-on-year volatility
Cutoffs swung from 75.41 (2023) to 92.66 (2025). Paper difficulty, not aspirant quality, drives this variance. Prepare for a 100 benchmark — then you're safe regardless of paper difficulty.

Out of 1750 marks. This is only the qualifying threshold for the interview call — final rank depends on the complete Mains + Interview aggregate out of 2025. Minimum 10% in each of the 7 papers also required.
42–43% is the floor
General category Mains cutoff has been 729–751 over 7 years (42–43% of 1750). To be safe from Mains elimination, target 750+. To be competitive for IAS, target 800+.
10% per paper is non-negotiable
25 marks out of 250 in each paper is the minimum. A catastrophic performance in one paper (even with a strong aggregate) means disqualification. Always attempt every paper fully.
Answer writing is the skill
Mains is entirely descriptive. 10-mark answers: 150–200 words. 15-mark: 250–300 words. Standard structure: Context → Analysis → Way Forward. Practice 3–4 answers daily from Month 6 onwards.

Out of 2025 marks total. 2025 final results declared 6 March 2026; 958 candidates recommended for appointment. PwBD detailed data for 2025 not separately published at time of update. For exact last-rank-by-service data, refer to the official UPSC allocation notification.
Target: 950+ for General
The 6-year range is 944–963. A score of 950+ (46.9%) comfortably clears any Central Service. To secure IAS, you need roughly 10–20 marks above the final cutoff — so 970+ is the IAS benchmark.
2025: highest since 2022
Gen cutoff jumped from 947 (2024) to 963 (2025) despite fewer seats (958 vs 1056). This confirms that fewer vacancies directly compress the cutoff upward. 2026 with only 933 seats may push it further.
SC/ST gap is 58–84 marks
SC cutoff is consistently 55–80 marks below General (2025: 905 vs 963 = 58 marks). ST tracks close to SC. Reservation applies to both the cutoff threshold and the vacancy count within each category.
Interview matters at the margin
At 275 marks, the interview can shift your aggregate by 30–50 marks relative to peers. Topper interviews average 175–210. For borderline candidates, a strong interview is the difference between IAS and IPS.

2026 notified vacancies as of notification date; final vacancies may increase. Inverse pattern: fewer seats → higher cutoff (compare 2022: 933 seats, cutoff 960 vs 2024: 1056 seats, cutoff 947).
109 days: Notification → Prelims
4 Feb → 24 May = 109 days. This is the final revision + mock test window. Your subject foundation should be complete before February. Use this window for test series, not new topics.
~6 weeks for Mains prep post-Prelims
Prelims result typically declared 6–8 weeks post-exam (~July 2026). Mains starts 21 Aug — giving roughly 5–7 weeks of dedicated Mains intensive. Your Mains foundation must be built during Prelims prep itself.
2026: fewer seats = higher competition
933 is the lowest since 2021 (712). The vacancy-cutoff inverse is historically consistent: expect a final cutoff of 955–970 for General category if the pattern holds, assuming similar Mains difficulty.

IAS cadre zones — 5 zones, 26 cadres
IAS/IPS/IFoS are allocated to state cadres using a 5-zone system. Zone I: AGMUT, J&K, HP, Uttarakhand, Punjab, Rajasthan, Haryana. Zone II: UP, Bihar, Jharkhand, Odisha. Zone III: Gujarat, Maharashtra, MP, CG. Zone IV: WB, Sikkim, Assam-Meghalaya, NE. Zone V: TN, Kerala, Karnataka, Telangana, AP. You rank zones in DAF — home-zone first = eligible for insider vacancy (1/3 of cadre seats).
IFS vs IAS — what top-rankers actually choose
IFS is often called "top-35" but actual allocation ranges from rank 1 to 120+ depending on how many top-rankers choose IAS over IFS. IFS offers tax-free foreign allowance, global postings, and a prestigious diplomatic career. IAS offers more direct governance power, field command at DM level, and greater domestic impact. Most top-10 rankers choose IAS; strong interest in foreign affairs and languages leads others to choose IFS first.
DAF preference is binding — research before you submit
Service preferences submitted in the DAF cannot be changed after submission. DoPT allocates services in strict AIR order — your highest available preference at the time your rank is processed. Getting the right service matters more than getting the right cadre — prioritise the service tier before worrying about state allocation. Full guidance: Service Deep-Dive Guide →
