Make a 2-column ledger: 'Year of Prelims' and 'Did I appear (yes/no)?' Count every YES. Subtract from your category cap (6/9/unlimited). Re-check age on 1 August of next exam year. Save the worksheet — UPSC won't remind you, the responsibility is yours.

UPSC doesn't send you a "3 attempts remaining" email. The onus is entirely on you — and a wrong declaration in the application can lead to cancellation and a future debarment under Rule 13 of the CSE Rules. Here's the mentor-recommended worksheet I give every new student.

Step 1 — Build your appearance ledger

Exam YearDid you appear in any Prelims paper?Counts as attempt?Evidence file
2020Yes / No1 or 0Admit card + OMR receipt
2021Yes / No1 or 0Admit card + OMR receipt
2022Yes / No1 or 0Admit card + OMR receipt
2023Yes / No1 or 0Admit card + OMR receipt
2024Yes / No1 or 0Admit card + OMR receipt
2025Yes / No1 or 0Admit card + OMR receipt
Total usedn / 6 or 9 or ∞

Rule: "Appear" = you were physically inside the exam hall and the OMR was handed to you. Withdrawn applications, no-shows, and pre-exam cancellations = 0.

Step 2 — Calculate balance by category

CategoryCapFormulaExample (3 used)
General66 − used3 remaining
EWS66 − used3 remaining
OBC-NCL99 − used6 remaining
SC∞ (age-bound)only age bindsuntil 37
ST∞ (age-bound)only age bindsuntil 37
PwBD-Gen/EWS/OBC99 − used6 remaining
PwBD-SC/ST∞ (age-bound)only age bindsuntil 47

Step 3 — Cross-check age ceiling

For CSE 2026, age is calculated on 1 August 2026. You must be ≥ 21 and ≤ your category ceiling (32 / 35 / 37 / 42 / 45 / 47). Use this quick calculator:

If you were born on or afterAnd on or beforeYou qualify (as on 1 Aug 2026)
02-Aug-199401-Aug-2005General/EWS
02-Aug-199101-Aug-2005OBC-NCL
02-Aug-198901-Aug-2005SC/ST
02-Aug-198401-Aug-2005PwBD-Gen/EWS
02-Aug-198101-Aug-2005PwBD-OBC
02-Aug-197901-Aug-2005PwBD-SC/ST

Step 4 — Build a forward planner

Once you know how many attempts and how many years remain, lay out the years grid:

Exam YearWill I appear?Confidence levelStrategic note
2026Y / NHigh / Med / LowThis is my Xth attempt
2027Y / NHigh / Med / LowHolding for optional change?
2028Y / NHigh / Med / LowBackup year

This prevents the "I'll figure it out next year" drift.

Step 5 — Document evidence

Keep in a single labelled cloud folder:

  • Admit cards of every Prelims you appeared in (proves which years counted).
  • Result PDFs / mark sheets from UPSC's official site.
  • OBC-NCL / SC-ST / PwBD certificates valid for the relevant FY.
  • EWS certificate if applicable (annual renewal).
  • Domicile certificate (for J&K/Ladakh applicants under the 2020 Rules).
  • Birth certificate or 10th board marksheet (UPSC accepts the latter as DOB proof).
  • Application acknowledgement for every year (PDF download at submission).

Step 6 — Honest disclosure on the next form

The DAF / application form asks for total attempts. Misdeclaration is the single biggest reason for candidature cancellation post-Interview — and it can also trigger debarment from future UPSC exams for 2-5 years under Rule 13. Even an honest miscount can derail you. Use the worksheet, double-check with a friend, then submit.

Worked example — Suraj's ledger

Suraj, OBC-NCL, DOB 15-Jul-2000 (turns 26 on 15-Jul-2026):

YearAppeared?Counter
2022Yes1
2023Yes (cleared Prelims, gave Mains)2
2024No (withdrew via window)2
2025Yes3
2026Will appearwill become 4

Attempts left after 2026: 5 (of 9). Age on 1-Aug-2026: 26. Age cap: 35. He has roughly 9 more potential cycles but only 5 attempts — for him, attempts will exhaust before age.

Mentor's note: I keep this worksheet pinned to my desktop and update it the evening of every Prelims. Five minutes saves five years.
