UPSC CMS Answer Key 2026 PDF: Release Date, Download
The UPSC CMS Answer Key for 2026 will only exist after the exam on 2 August 2026, and even then UPSC rarely publishes an official key for CMS the way many sites claim. This guide explains what UPSC actually releases, when unofficial keys typically appear, and how to calculate your own score correctly.
Last updated
The UPSC CMS 2026 Answer Key does not exist yet; the Combined Medical Services exam itself is scheduled for 2 August 2026.
But there is a bigger point most articles on this topic skip entirely: UPSC has never published a standalone official answer key for the CMS written exam, even in years when the exam is long over.
What you will actually find, and when, is different from what most search results promise. This guide sets that straight, then walks through the unofficial answer key timeline, the response sheet facility, and exactly how to calculate your own score once papers are attempted.

An answer key needs a conducted exam behind it, and the UPSC CMS Answer Key 2026 cannot exist before the written test on 2 August 2026.
Searching for the UPSC CMS 2026 Answer Key before that date will only turn up guesses or old papers relabelled. Nothing genuine can exist before that date.
Once both papers are done, two separate things happen on two very different timelines, and knowing the difference saves you weeks of pointless refreshing on the wrong page.
UPSC CMS Question Paper 2026
This is the part most competing articles get wrong, and it is worth explaining properly.
UPSC's own responses to Right to Information (RTI) applications, filed repeatedly by aspirants over the years for exams like CDS, CAPF, IES, and IFoS, state that the Commission does not disclose its official answer key until the "entire examination process is over."
For a two-stage exam like CMS, that means after the written test result, the Personality Test, and the final merit list, not within a few weeks of the written exam.
Even the flagship Civil Services Preliminary Examination, which does eventually get an official answer key thanks to a Central Information Commission ruling, only sees that key published long after Prelims itself, once the full annual cycle closes.
In plain terms: if you see a page promising the "official UPSC CMS Answer Key" within two weeks of the exam, treat that claim with caution.
Based on past CMS cycles, no such standalone key has appeared that quickly, and often none appears at all in a form open to the public.
What UPSC Does Publish Instead
Two things genuinely come from UPSC after a CBT-mode exam like CMS:
A response sheet facility. UPSC opens a short window on upsc.gov.in where you can log in and view the responses you actually marked during the exam. This confirms what you selected; it does not tell you which answers were correct.
Cutoff marks after the full process. Once the written result, Personality Test, and final result are all declared, UPSC releases category-wise cutoff marks. These help you judge where you stood, without ever confirming answer-by-answer accuracy.
Neither of these is the "answer key" most aspirants picture, and no CMS cycle in recent memory has produced one in the days after the exam.
Add as a preferred Source on Google
Since the official gap is real, the practical resource for same-week self-assessment is the unofficial answer key published by coaching platforms.
Several institutes reconstruct both papers from candidate recall and publish a marked answer key within hours of the last session ending.
Treat it as a working estimate, not gospel. A handful of options can be disputed even among coaching experts, particularly on borderline clinical judgement questions in Surgery and Preventive and Social Medicine.
The sensible approach: check your score against at least two or three independently published keys before trusting a single number.

For the UPSC CMS Answer Key 2026 cycle, this puts the written result realistically around mid to late September 2026, with the final result likely landing sometime between December 2026 and February 2027.
Once UPSC activates the facility, the steps are straightforward:
Visit the official UPSC website, upsc.gov.in.
Go to the Examinations tab and look for the Response Sheet or Recruitment Test section.
Select Combined Medical Services Examination 2026.
Log in with your Registration ID or Roll Number and date of birth.
View and download your recorded responses.
Cross-check this against the unofficial answer key to calculate your likely score.
This step is genuinely useful and often skipped, since your own response sheet confirms exactly which option got recorded against each question, which matters when an exam-hall mistake looks different from what you remember typing.
Each paper carries 120 questions for 250 marks, so each question is worth roughly 2.08 marks. A wrong answer costs one-third of that, close to 0.69 marks.
Formula: Score = (Correct answers × 2.08) − (Wrong answers × 0.69)
Example: If you attempt 100 questions in Paper I with 78 correct and 22 wrong, your estimated score is (78 × 2.08) − (22 × 0.69), which works out to roughly 162 minus 15, or about 147 marks out of 250.
Run this calculation for both papers separately, then add the two for your estimated written total out of 500. Compare that against the cutoff table below to judge where you stand.
Cutoffs give the self-assessment real context. Here is the written and final cutoff for CMS 2025, Category I posts:
Category | Written Cutoff (out of 500) | Final Cutoff (out of 600) |
General | 290.24 | 380.20 |
EWS | 251.18 | 358.29 |
OBC | 278.20 | 372.54 |
SC | 243.30 | 325.84 |
ST | 222.49 | 310.08 |

In 2024, the General category written cutoff sat higher at 309 out of 500. The swing between cycles is a reminder not to chase last year's exact number; aim comfortably above it.
A few habits quietly inflate or deflate your self-estimate:
Relying on a single coaching platform's key without cross-checking a second source.
Forgetting to apply negative marking to unattempted-but-marked-for-review questions that were actually submitted.
Mixing up Paper I and Paper II answer keys when the question numbering resets for each paper.
Treating a disputed question as automatically correct in your favour before any official clarity exists.
