Quick Reply: NDA and CDS each run twice a year — UPSC publishes the calendar with NDA and Naval Academy Examination I and II, and CDS I and II. The chain is written exam, SSB interview, medicals, merit list. A candidate declared unfit by the medical board may appeal to an Appeal Medical Board within 42 days. UPSC answers RTI as a public authority through rtionline.gov.in — marks, cut-offs and selection records are reachable, and answer sheets are information under the Supreme Court's 2011 ruling.
Frequency: NDA (I) and (II); CDS (I) and (II) — every year
Conducting body: UPSC — written result, common cut-offs
SSB: Services Selection Board interview and medicals follow qualification
Medical appeal: Appeal Medical Board, within 42 days of the unfit finding
RTI route: UPSC CPIO via rtionline.gov.in; SSB records via the parent ministry
NDA and CDS differ from most UPSC exams in one structural way: the written score is only the gate. The final merit list is built after the SSB interview and medicals, conducted by the Services, not UPSC. That split decides where each of your records sits — and therefore where each RTI goes.
Every cycle produces two distinct numbers: the written cut-off that called candidates to SSB, and the final cut-off after SSB marks. Comparing your case against the wrong one misreads it by a wide margin — and both, with the marks of non-qualified candidates, are published after the cycle and reachable by RTI before that.
A workable UPSC application:
1. My paper-wise marks in NDA (II) 2026, roll no. ___. 2. The cut-off applied to qualify candidates for SSB in my paper combination, and the number qualified. 3. The methodology note or record showing how the cut-off was fixed. 4. The number of candidates who appeared, qualified the written stage, and were recommended finally. 5. The date of publication of the answer key and the objections received on question ___ of paper ___.
Real example. Kashvi Pathak's CDS written score sat a few marks above her expectation but below the published qualifying line in her subject combination. One RTI brought the subject-wise break-up and the cut-off computation — which showed her optional-combination cut-off had moved four marks above her total. No wrong had occurred, but the exact arithmetic replaced a season of doubt, in 28 days and ₹10.
Twice each — the UPSC calendar carries NDA and Naval Academy Examination I and II, and CDS I and II, every year.
Yes — an Appeal Medical Board within 42 days of the unfit finding, and a Review Medical Board beyond that in defined circumstances.
Yes — UPSC is a public authority; marks, cut-offs and evaluation records answer under the Act, filed at ₹10 through rtionline.gov.in.
Evaluation records are information — the Supreme Court's 2011 ruling in the CBSE case — through the authority's own disclosure procedures first, RTI where the file stalls. The full route is on the answer-sheet page.
Last reviewed: 26 August 2026. The twice-yearly cycle confirmed against the UPSC calendar; the 42-day Appeal Medical Board window re-checked against the SSB medical procedure as published for NDA entries.
