How many UPSC attempts do I get for each category — and what counts as an attempt?

Category-wise Attempt Ceiling

Per Para 4 of the CSE 2026 Notification (4 February 2026):

The binding constraint is whichever comes first — attempts or age. A General candidate who has used all 6 attempts by age 28 is done; an SC candidate has unlimited attempts but still must be under 37 on 1 August of the exam year.

What Officially Counts as an Attempt

This is the most misunderstood rule in the entire eligibility framework. Per UPSC's notification and the Examination Branch FAQ:

• Appearing in any one paper of Prelims = 1 attempt. Even if you walked into the centre, signed the attendance, and left blank — it counts.
• Filling the form and not appearing ≠ attempt. If you applied, paid the fee, but never entered the exam hall, no attempt is consumed.
• Disqualified candidature (e.g., for not meeting eligibility from the start) ≠ attempt.
• Mains/Interview appearances do NOT consume an additional attempt — only Prelims does.
• CSAT failure (i.e., not getting 33% in Paper-II) still counts as one attempt because you appeared.

Don't Waste an Attempt on a 'Practice Round'

Historically, a large share of registered candidates — often close to half — do not actually appear in Prelims, and those who stay home do not consume an attempt. (Year-wise registration and appearance figures are published in UPSC's Annual Reports; check those for exact numbers.) The lesson: if you are under-prepared, sitting Prelims as a "practice round" burns an attempt you can never reclaim.

Worked Example — Ravi, OBC, born 12 July 1998

• 2020 — filled form, didn't appear → 0 attempts
• 2021 — appeared in Prelims, failed → 1 attempt
• 2022 — reached Interview, didn't make the list → 2 attempts
• 2023 — appeared in Prelims → 3 attempts
• 2024 — appeared in Prelims → 4 attempts
• 2025 — appeared in Prelims → 5 attempts

Ravi has 4 attempts left (out of 9) and his upper age cap as OBC is 35 (born 12 Jul 1998 → turns 35 on 12 July 2033, so eligible up to CSE 2033). He has both attempts and age room — comfortable.

Worked Example — A General Candidate Running Out

If you are General, born 5 February 1996, and have appeared in CSE 2019, 2020, 2021, 2022, and 2023:

• Attempts used: 5 of 6 → 1 left.
• Age on 1 Aug 2026: 30 years 6 months.
• You can sit CSE 2026, but if you don't clear, CSE 2027 is your last attempt since by 1 Aug 2027 you'll still be 31 (under 32 cap). For CSE 2028, you'd be 32 years 6 months — over the cap. So your true deadline is CSE 2027.

Topper Insight — Attempts Are Not Wasted

Anudeep Durishetty topped CSE 2017 (AIR-1) on his fifth attempt, having joined the IRS after an earlier rank before re-attempting (he writes about this journey on his blog, anudeepdurishetty.in). Shakti Dubey topped CSE 2024 (AIR-1) on her fifth attempt. Two of the most recent toppers needed five cycles each — earlier attempts build the Mains-writing, CSAT-timing and interview skills that finally convert.

Special Note for Serving Officers (CSE 2026 Onwards)

Under the new CSE 2026 rules, serving IAS and IFS officers cannot reappear without resigning, regardless of attempts left. Serving IPS officers can reappear for non-IPS services but cannot re-pick IPS. See the FAQ on serving-officer reattempts for the full mechanic.

Recent Policy Change — The Khedkar Aftermath

Following the Puja Khedkar disqualification (UPSC press release, 31 July 2024), UPSC has tightened identity verification: from CSE 2025 onwards, Aadhaar-based biometric authentication is being trialled at major exam centres. While this doesn't change the attempt count, it makes impersonation-led 'extra attempts' impossible. UPSC's 2 August 2024 statement explicitly noted that any future fraud will result in lifetime debarment.
