How CDS merit and cut-offs work

Clearing the written exam depends on academy-wise cut-offs; final selection depends on written plus SSB marks, medical fitness and your preferences. How the pieces fit together, with worked examples, and what it means for preparation.

A CDS result has three separate hurdles: the written cut-off that gets you to the SSB, the SSB recommendation itself, and the final merit list that decides who joins which academy. Candidates often treat "the cut-off" as a single number to beat. It is not. There is a cut-off for each academy, a minimum in each paper, and a final merit position that depends on marks you have not earned yet when you sit the written exam.

This guide explains each stage, works through examples, and draws out what it means for how you prepare.

Stage 1: the written cut-off

UPSC sets written cut-offs separately for each academy, and publishes them after the final result. They depend on:

  • the number of vacancies for that academy in that cycle,
  • the difficulty of the papers,
  • the number of candidates and how they performed.

The cut-off is on the total for that academy's papers: out of 300 for IMA, INA and AFA, and out of 200 for OTA.

There is also a minimum in each paper. UPSC has the discretion to fix qualifying marks in any or all subjects, and a candidate who falls below the minimum in one paper is not called to the SSB, however high the total. Secondary sources commonly report this minimum as around 20 per cent per paper.

What "academy-wise" means in practice

Because each academy has its own cut-off, a candidate can clear one and not another. Consider a hypothetical candidate who applies for IMA and OTA and scores:

PaperMarks
English58
GK42
Maths22
  • IMA total: 58 + 42 + 22 = 122 out of 300.
  • OTA total: 58 + 42 = 100 out of 200.

Suppose, for illustration only, that the IMA cut-off that cycle was 125 and the OTA cut-off 95. This candidate misses IMA by 3 marks but clears OTA by 5. Maths, which counts only for IMA, made the difference. A further 4 marks in maths would have cleared both.

Stage 2: the SSB

Candidates who clear the written cut-off for an academy are called to the SSB. The board either recommends or does not recommend a candidate; there is no partial pass.

AcademySSB marks
IMA, INA, AFA300
OTA200

Recommended candidates then face a medical examination. Only candidates who are recommended and declared medically fit go on to the final merit list. AFA candidates must also clear the CPSS at the SSB. For the full process, see the SSB overview.

Stage 3: final merit

IMA, INA, AFA300300600
OTA200200400

Final merit lists are prepared academy-wise. Your position depends on your total, and then on vacancies, your preferences and your medical fitness.

A worked comparison

Three hypothetical candidates, all recommended and fit, compete for IMA:

CandidateWritten (of 300)SSB (of 300)Final (of 600)Rank
P1752153901
Q1402453852
R1901803703

R had the highest written score by some distance and finished third. Q had the lowest written score of the three and finished second on the strength of the SSB. The SSB carries half the final marks, and SSB marks vary widely between candidates.

Preferences and allotment

You rank the academies you are eligible for on your application. If you are recommended, fit and high enough in merit, you are allotted according to your preferences and the vacancies:

  1. If you are in merit for your first preference, you are allotted to it.
  2. If not, you are considered for your next preference, and so on.
  3. You are never allotted an academy you did not list.

So list only the academies you would genuinely join, in the order you actually prefer them. Putting an academy lower in the list because its cut-off looked easier can leave you with a career you did not want. The guide to what each academy offers helps with this choice.

Why cut-offs move

FactorEffect on cut-off
More vacancies at an academyTends to lower it
An easier paperTends to raise it
More candidates, or stronger performanceTends to raise it
A tougher maths paperTends to lower IMA, INA and AFA cut-offs; OTA uses no maths

This is why chasing last cycle's number is a weak strategy. A score that cleared comfortably one year can fall short the next.

What this means for preparation

  • Aim comfortably above recent cut-offs for your preferred academy in your practice papers, not just at them. A margin of 15 to 20 marks gives room for a bad day.
  • Do not neglect any paper. Each has a minimum, and a weak paper can stop you even with a strong total.
  • Prepare for the SSB alongside the written exam. It carries half the final marks, and the gap between the written result and the SSB is short.
  • Stay fit and check medical standards early. A recommendation is worth nothing without medical fitness.
  • Take your preference list seriously. It decides where you end up.

Common mistakes

  • Treating one cut-off figure from a website as fixed.
  • Ignoring the per-paper minimum because the total looks safe.
  • Assuming a high written score makes the SSB a formality.
  • Listing academies as "backups" without being willing to join them.

Practice

  1. A candidate scores English 61, GK 47, Maths 30. What are their IMA and OTA written totals? IMA: 61 + 47 + 30 = 138 of 300. OTA: 61 + 47 = 108 of 200.
  2. The same candidate gets 230 at the SSB for IMA. What is the final IMA total? 138 + 230 = 368 of 600.
  3. Can a candidate clear the OTA cut-off but not the IMA cut-off in the same cycle? Yes. Cut-offs are academy-wise, and maths counts only for IMA, INA and AFA.
  4. A candidate is recommended but found medically unfit. Do they appear in the final merit list? No. Medical fitness is a condition of the final list, subject to the appeal process in the rules.
  5. Can you be allotted an academy you did not list? No.

What to do next

  • Find the official marks and cut-off notices for the last three cycles on upsc.gov.in
  • Note the cut-off for each academy on your list, as a percentage of its total
  • Set your practice-paper target 15 to 20 marks above the highest recent figure
  • Check your weakest paper against a 20 per cent floor, and fix it first if it is close
  • Start SSB preparation now, not after the written result

For the scoring arithmetic behind all this, read negative marking in CDS, and for the structure of the whole exam, the CDS exam pattern.
