UPSC CDS 2026: Important Dates, Eligibility, Application Steps and FAQs
UPSC CDS is a graduate-level defence-entry route for candidates targeting IMA, INA, AFA and OTA. It requires academic eligibility, service-wise preference planning, written preparation and SSB readiness.
CDS applicants should not choose preferences casually. Education stream, age range, marital status, medical standards and training academy expectations can all affect eligibility and final allocation.
Important Dates Table
| Notification release | Check the official notification page. Do not rely on forwarded screenshots or old-cycle PDFs. |

| Last date to apply | Verify the final deadline, fee deadline and correction-window dates from the official notice. |
| Admit card / call letter | Usually released before the exam stage on the official website or linked portal. |

Detailed Eligibility Criteria
| Education | Graduation rules differ for IMA/OTA and technical/science requirements may apply for INA/AFA. |
|---|---|
| Service preference | Choose IMA, INA, AFA or OTA only after matching education and age rules. |
| Medical standards | Defence medical standards must be read before applying. |
| SSB readiness | Personality, communication and leadership assessment are central after written qualification. |
Age Limit and Relaxation

Expected Cut-off and Benchmark Notes
CDS cut-offs must be understood academy-wise. Written qualifying marks and final marks after SSB differ, so candidates should not judge readiness by one combined number.
Exam Pattern and Syllabus Focus
| Written exam | English, General Knowledge and Elementary Mathematics for some academies; OTA pattern differs. |
|---|---|
| SSB | Interview, psychological tests, GTO tasks and conference. |
| Medical/final merit | Medical examination and service-wise merit. |
Strategic Study Timeline
Use five to six months: English and GK daily, mathematics for IMA/INA/AFA routes, previous papers weekly and SSB communication practice from month one.
Common Mistakes Applicants Make
Mistakes include wrong academy preference, ignoring OTA pattern difference, weak current affairs and starting SSB practice only after result.
