Marking System, Cut-offs & Attempts

How UPSC CSE marks, cut-offs, negative marking, attempts and rank actually work — and what your score targets should be.

Last reviewed: August 2026

The Complete Selection System

Prelims cutoff is based on GS Paper-I (CSAT qualifying). Qualifiers write Mains (1750). A Mains cutoff decides who reaches the Interview (275). Final = 2025 marks decides rank.

The most important thing
Prelims marks are NOT added to your final rank. Final rank comes from Mains Written 1750 + Interview 275 = 2025.

Prelims Cut-off & Negative Marking

• CSAT is qualifying at 33% — you must score 66/200 — but the actual Prelims cutoff is determined by GS Paper-I.
• A published cutoff (e.g. General = 87.98) means candidates around that level or above in GS-I were shortlisted; it does NOT mean 88 marks makes you safe next year.
• Why the cutoff changes yearly: paper difficulty (easy paper raises it, hard paper lowers it), number of vacancies, number and performance of candidates, and question distribution.
• Never target the previous cutoff. If last year's was 90, target a safety zone like 105-115+ — a preparation target, not a cutoff prediction.

Negative marking: +2 / -2/3
For most questions, correct = +2 and incorrect = -2/3. Example: 60 correct + 30 wrong = 120 - 20 = 100. Random guessing drops your score quickly, so accuracy and question selection are critical.

CSAT — the dangerous paper
Don't target just 66: calculation mistakes happen, comprehension can be difficult, question selection matters and difficulty varies. Aim comfortably above qualifying — 90+ in practice if possible. If maths/reasoning is weak, prepare CSAT from the beginning.

Attempts & Age Limit

• An attempt is generally counted when you actually appear in at least one Prelims paper — merely submitting the application does not normally consume an attempt.
• General category upper age limit is usually 32 years, with prescribed relaxations for eligible categories.
• Your real constraint is age + attempts + preparation level — don't plan only around the number 6.
• Don't attempt every year casually. Ideally your first serious attempt should already be treated as a final-level attempt.

Avoid the 'attempt mentality'
'I'll give Prelims just for experience' can waste an attempt. When you enter the exam hall, you are trying to qualify. One well-prepared attempt beats multiple casual attempts.

Mains Marks — The Real Game

There is no permanent 'good score' — difficulty and competition change, and the same score can produce different ranks in different years. Example profiles: a candidate scoring Essay 125, GS-I 105, GS-II 110, GS-III 100, GS-IV 120, Optional 140+145 = 845 is decent but would likely need more to be competitive; Essay 145, GS-I 120, GS-II 125, GS-III 120, GS-IV 130, Optional 155+155 = 950 is a much stronger profile. The two language papers are qualifying and are not added to merit.

Optional can dramatically change your rank
Optional = 500/1750, about 28.6% of Mains written marks. Two candidates with identical GS + Essay (650) but Optionals of 250 vs 350 end at 900 vs 1000 — a 100-mark gap purely from Optional. Choose it seriously.

Interview & Final Calculation

• Interview = 275 marks, about 13.6% of the 2025 final merit. Mains dominates, but interview is not negligible.
• Example: A (Mains 950 + Interview 180 = 1130) beats B (900 + 220 = 1120), but C (900 + 240 = 1140) beats both — the interview can move rank significantly.
• A strong interview can compensate for some Mains deficit; a weak interview can pull down a strong Mains score.
• Sample final calculation: Mains 950 + Interview 210 = 1160/2025, roughly 57.3%. Even successful candidates may have final percentages that don't look high.

Why 50-60% can be enough for a very good rank
You're competing against a large pool of highly prepared candidates. You aren't trying to score 90% — you're trying to score higher than the competition. UPSC is fundamentally a relative-performance examination.

The Three Cut-offs, Rank & Service

1. Cutoff 1 — Prelims — Determines who reaches Mains. Based primarily on GS Paper-I, with CSAT qualifying.
2. Cutoff 2 — Mains — Determines who is called for the Personality Test. Based on Mains merit papers, with qualifying papers cleared.
3. Cutoff 3 — Final — Determines the final merit list. Based on Mains + Interview.

• UPSC publishes category-wise cutoffs (General, EWS, OBC, SC, ST, PwBD categories) — the cutoff is not the same for everyone, and Prelims, Mains and Final cutoffs are three different numbers.
• Example journey: GS-I 108 + CSAT 92 clears Prelims; Mains 925/1750 clears the Mains cutoff; Interview 215 gives Final 1140/2025 — then rank depends on how everyone else performed.
• Final rank depends on final marks + category + vacancies + service allocation rules/preferences. Even 5-10 marks can matter substantially around competitive rank bands.
• Rank 100 is not automatically IAS. Service allocation (IAS, IPS, IFS, IRS, other Group A/B services) depends on rank, category, vacancies, preferences and allocation rules — the final qualifying cutoff and the rank needed for a particular service are different things.
• Don't compare raw marks across years blindly — paper difficulty, evaluation trends, interview distributions, optional difficulty, candidate performance and vacancies all vary. Rank and percentile context matter more than raw marks.

What Your Targets Should Be

Instead of obsessing over historical cutoffs, set internal preparation targets.

Improve the weakest paper first
If your mocks show Essay 120, GS-I 105, GS-II 85, GS-III 105, GS-IV 125, Optional 290 (total 830), don't try to improve everything at once. Lifting GS-II from 85 to 110 adds +25 marks — far more efficient than moving every paper by 5.

• The biggest rank-improvement opportunities: Optional (500 marks), Essay (250), GS answer quality (1000 across four papers), Interview (275).
• Beginner timeline: first 6 months — build foundation, ignore attempt counting; 6-9 months — serious Prelims + Mains integration; 9-12 months — full tests; exam year — treat it as your serious attempt.

Attempt Strategy Inside Prelims

The number of questions you attempt is not fixed. Candidate A attempting 90 with 70 correct + 20 wrong scores 140 - 13.33 = 126.67. Candidate B attempting 75 with 65 correct + 10 wrong scores 130 - 6.67 = 123.33 — A wins. But if B manages 68 correct + 7 wrong, B scores 136 - 4.67 = 131.33 and wins. The right question is not 'how many should I attempt?' but 'at what attempt level can I maintain high accuracy?'

• During mocks, record attempts, correct, wrong and score for every test to identify your optimal attempt range.
• Don't blindly copy a topper's 'I attempt 85 questions' — your accuracy profile is different.

The real UPSC marks game
Prelims: qualify (not 'highest score'). Mains: maximize — it's 1750 marks. Interview: stabilize + maximize — 275 marks can significantly change your final position.

Score Mindset & Five Rules to Remember

A psychological trap
'Last year's cutoff was 90', 'Rank 100 scored 1050', 'IAS required X marks' — useful for analysis, dangerous as preparation targets. Your real targets: syllabus completion > PYQ mastery > mock performance > answer quality > revision > final score.

1. Prelims marks don't count in final merit.
2. CSAT is qualifying but cannot be ignored.
3. Mains = 1750 marks and is the biggest scoring opportunity.
4. Optional = 500 marks, so choose it carefully.
5. Final rank = Mains + Interview, not Prelims + Mains + Interview.

Three-zone score mindset
Prelims: comfortable qualification, never the bare minimum. Mains: 900+ type performance as a broad benchmark, not a guaranteed threshold. Final: strong Mains + competitive interview, because the result depends on the whole pool.
