About CDS

What is CDS?

The Combined Defence Services Examination is UPSC's graduate-entry examination for admission to notified courses at the Indian Military Academy, Indian Naval Academy, Air Force Academy and Officers' Training Academy. CDS I and CDS II are two cycles of the same examination, not separate career routes.

The academy selected changes both eligibility and the written pattern. Candidates for IMA, INA and AFA take English, General Knowledge and Elementary Mathematics, while OTA candidates take English and General Knowledge only. Educational, age, sex and marital-status rules must therefore be checked academy by academy.

Written qualifiers proceed to service selection-board assessment and medical examination. Final admission depends on written and SSB marks, medical fitness, eligibility, stated preferences and the vacancies available for the relevant course.

These are original-notification vacancy totals for CDS II cycles, not final intake or appointments. UPSC describes the notified counts as approximate or tentative and Service Headquarters may change them. The 2023 figure is omitted because its academy and OTA components were verified across separate official releases rather than one directly citable notification source.

UPSC CDS Application Process and Fees

Official application route and fee details

The CDS II 2026 application window is closed. Future applicants should open the newest notification and live UPSC examination page rather than reuse the dates, vacancies or eligibility windows from this cycle.

The current UPSC flow uses Account Creation, Universal Registration, the Common Application Form and an examination-specific module. Complete the requested identity, education, photograph, live-photograph and signature steps only through the official portal.

Choose academy preferences only after checking each route's qualification, age and medical rules. The CDS II 2026 notice requires AFA to be the first preference for candidates seeking that academy and includes separate preference instructions for OTA.

Review every field before submission and retain both the Universal Registration Number and the examination-specific application number. Admission remains provisional until documentary eligibility is verified.

UPSC CDS Syllabus Overview

Subjects and stages in the official syllabus

  • English tests understanding of English and effective use of words. Use official previous papers to identify the recurring comprehension, grammar, usage and vocabulary demands.
  • General Knowledge includes current events, everyday observation and scientific aspects, History of India and Geography at the level described in the official syllabus.
  • Elementary Mathematics covers arithmetic, elementary number theory, algebra, trigonometry, geometry, mensuration and statistics. It is approximately matriculation level and applies to IMA, INA and AFA, not OTA.
  • The English and General Knowledge papers are approximately at the level expected of a graduate of an Indian university.
  • SSB Stage I uses Officer Intelligence Rating tests and Picture Perception and Description Test. Stage II includes interview, Group Testing Officer tasks, psychology tests and conference.

English

Understanding, comprehension and effective use of English; compulsory for every CDS academy route.

General Knowledge

Current events, everyday science, History of India and Geography; compulsory for every route.

Elementary Mathematics

Arithmetic, number theory, algebra, trigonometry, geometry, mensuration and statistics at matriculation level; not taken by OTA candidates.

SSB and AFSB assessment

Stage I OIR and PP&DT screening, followed by Stage II interview, group tasks, psychology tests and conference.

CDS II 2026 Answer Key Status

The written examination has not yet been held

Not released

Current status: No official CDS II 2026 answer key was published as of 2 August 2026.

The written examination is scheduled for 13 September 2026, so any key circulated before the papers are held is not an official CDS II 2026 answer key.

After the examination, use UPSC's official publication and representation channels. Coaching keys may support informal review but should not be presented as UPSC's answer key.

CDS 2026 Result Status

CDS I result published; CDS II result awaited

Partly published

Current status: UPSC published the CDS I 2026 written result on 8 May and the name-wise result on 20 May; no CDS II 2026 result existed as of 2 August.

UPSC reported 8,826 candidates qualified in the CDS I 2026 written examination. Written qualification advances a candidate to service-specific SSB/AFSB processing; it is not final academy admission.

CDS II 2026 is still before the written stage. Its result date should remain unpublished until UPSC posts the result document.

UPSC CDS Cut-off Marks

Use historical cut-offs as context, not a prediction

Not published

Current status: Official CDS I or CDS II 2026 cut-off marks were not published as of 2 August 2026.

UPSC publishes academy-specific written and final cut-offs after the selection process. The threshold varies by academy, cycle, vacancies, paper difficulty and candidate performance.

In both historical tables below, UPSC applied a minimum of 20 percent in each written paper. Meeting that paper-wise minimum alone did not guarantee the academy-level written or final cut-off.

Academy Routes and Officer Pay

How academy choice changes the route, papers and notified pay

CDS is one examination feeding different academy and commission routes. Academy choice changes educational eligibility, written papers, service assessment and the form of commission or training outcome.

Pay figures below are basic notified amounts, not take-home salary. Allowances, deductions, posting, accommodation and prevailing service rules affect the amount received.

  • Indian Military Academy — Army permanent commission route
  • Indian Naval Academy — notified Indian Navy academy route
  • Air Force Academy — Air Force pre-flying training route
  • Officers' Training Academy — Army Short Service Commission (Non-Technical) men's and women's entries

UPSC CDS Preparation Strategy

A syllabus-first preparation route

  1. Choose the academy route before building a study plan. OTA candidates should not spend preparation time on an Elementary Mathematics paper they will not take.
  2. Begin with an official previous paper under timed conditions. Record accuracy and weak topics separately for English, General Knowledge and, where applicable, Mathematics.
  3. Build Mathematics from Class VI–X fundamentals, then move to timed mixed sets. Because wrong answers lose marks, review calculation and selection errors rather than chasing attempt count alone.
  4. For English, combine reading and comprehension with regular grammar, usage and vocabulary practice based on the style of official CDS papers.
  5. For General Knowledge, connect current affairs to compact foundations in history, geography and everyday science. Use one revision system instead of collecting overlapping compilations.
  6. Practise complete two-hour papers and review every wrong, guessed and skipped item. Accuracy under the negative-marking rule is a core exam skill.
  7. Prepare for SSB alongside written study through honest self-awareness, communication, observation, fitness and constructive group participation. Do not rely on memorised personality scripts.

CDS Books and Study Material

  • Keep the official notification, syllabus and UPSC previous papers as the source-of-truth stack.
  • Use NCERT Mathematics from Classes VI–X to repair Elementary Mathematics fundamentals before moving to timed CDS practice.
  • Use selected NCERT Science, History and Geography texts for General Knowledge foundations, guided by official papers.
  • Use one dependable English grammar and usage reference plus comprehension practice; several overlapping books are harder to revise.
  • For SSB and service procedures, prefer the official Army, Navy and Air Force information pages over coaching claims.

UPSC CDS Previous Question Papers

Official question-paper resources

Official papers show the actual level, paper mix and time pressure. OTA candidates need English and General Knowledge papers; IMA, INA and AFA candidates should also attempt Elementary Mathematics.

Attempt a full paper first, classify mistakes by syllabus area, revise the weak areas and then retake an equivalent paper under the same two-hour limit.

UPSC CDS Frequently Asked Questions

What is the current status of CDS II 2026?

The application window is closed and the written examination is scheduled for 13 September 2026. No exact admit-card or written-result date should be shown until UPSC publishes it.

What is the CDS exam?

CDS is UPSC's graduate-entry examination for notified courses at IMA, INA, AFA and OTA. Selection includes objective written papers, SSB or AFSB assessment, medical examination and route-wise final merit.

Are CDS I and CDS II different exams?

They are two cycles of the same Combined Defence Services Examination. The dates, course numbers, vacancies and exact eligibility windows change, so candidates must use the notification for their own cycle.

Is Mathematics compulsory in CDS?

Elementary Mathematics is compulsory for IMA, INA and AFA candidates. OTA candidates take only English and General Knowledge.

Can final-year students apply for CDS?

Eligible final-year or final-semester students may apply where the notice permits, but they must produce proof of passing by the academy-specific deadline and meet the document conditions at SSB.

Are women eligible for CDS?

The CDS II 2026 notice considers women for the notified OTA Short Service Commission women's course, subject to its age, degree and marital-status conditions.

What qualification is required for CDS?

IMA and OTA require a recognised degree or equivalent. INA and AFA have additional degree or Physics–Mathematics requirements, so qualification must be checked academy by academy.

How many papers are there in CDS?

IMA, INA and AFA candidates take three two-hour papers worth 100 marks each. OTA candidates take two two-hour papers worth 100 marks each.

Is there negative marking in CDS?

Yes. One-third of the marks assigned to a question is deducted for a wrong answer. A blank response carries no penalty.

What happens after the CDS written result?

Written-qualified candidates follow the relevant service's call-up or registration process for SSB or AFSB. Those who pass the two-stage assessment proceed through service medical and final merit requirements.

Does clearing the CDS written exam guarantee selection?

No. Candidates must separately meet the SSB standard, medical and documentary eligibility, and rank within the vacancies for the relevant academy and course.

What is the difference between IMA and OTA through CDS?

IMA is an Army permanent-commission route and its written exam includes Elementary Mathematics. OTA is an Army Short Service Commission route and its written exam has only English and General Knowledge.

Can a candidate choose more than one CDS academy?

A candidate may state multiple eligible preferences subject to the current notice's ordering rules. For CDS II 2026, candidates seeking AFA must place it first, and OTA has additional preference instructions.

What is a safe CDS cut-off score?

There is no fixed safe score. Written and final cut-offs vary by academy and cycle. Historical official cut-offs are useful context, but they do not predict CDS II 2026.

Are CDS medical standards the same for every academy?

No. Medical, visual and role-specific conditions vary by service and academy. Candidates should use the medical appendix in the current UPSC notice and the relevant service process page.
