UPSC CMS Answer Key 2026 Out: Download Paper 1 & 2 Response Sheet PDF

UPSC CMS Answer Key 2026 has been released by the Union Public Service Commission (UPSC) on its official website for the Combined Medical Services (CMS) Exam 2026. UPSC CMS 2026 Computer-Based Test (CBT) was conducted on 2 August 2026 to fill 1,359 vacancies in the Central Health Service, Railways, and Municipal Bodies. Candidates can download the provisional answer key and response sheet for General Medicine, Pediatrics, Surgery, Gynaecology & Obstetrics, and Preventive & Social Medicine (PSM). The Commission has also opened the objection facility for candidates to challenge any discrepancies in the provisional answer key.

UPSC CMS 2026: The New Provisional Key Policy Explained

UPSC has historically held back its answer key until well after a recruitment cycle has finished, sometimes over a year later, leaving CMS candidates to rely entirely on coaching institutes' estimates. That changed for the first time in 2026.

• In a written reply to the Rajya Sabha in March 2026, the government confirmed UPSC had formulated guidelines to release a provisional answer key on its own website right after conducting an exam, in compliance with a Supreme Court judgement.
• The reply specifically stated this process would apply to all structured Exams conducted by UPSC, starting with the Civil Services Preliminary Exam 2026 and extending across the commission's other tests.
• NDA and CDS (I) 2026, held April 12, got their provisional keys just 4 days later, on April 16, the first time either exam had ever seen an official key before results.
• Civil Services Prelims 2026, held May 24, followed the same pattern, with its provisional key out around May 27 and a window to raise objections through May 31.

UPSC CMS 2026 QPRep Objection Process and Why There Is No Fee

QPRep itself is not new. UPSC has run this portal since around 2018 to let candidates flag a wrongly framed question, but the 2026 reform widened what it actually covers for CMS and every other structured exam.

1. Log in to upsconline.nic.in with the roll number and date of birth used for CMS registration.
2. Open the Representations on Question Paper and Provisional Answer Keys link once it is active for CMS 2026.
3. Select the paper, subject, and question number being challenged.
4. Write the justification and attach a scanned reference from a standard textbook or authentic source.
5. Submit before the window closes. Nothing is accepted after that point through any other channel.

UPSC CMS 2026 Paper 1 and Paper 2, Why the Key Splits in Two

In UPSC CMS 2026 Paper 1 and Paper 2 cover entirely different clinical subjects, so a candidate needs both halves of the key rather than a single combined sheet to check either paper's responses.

How to Check UPSC CMS 2026 Answer Key Once It Is Released

The key will sit on UPSC's own site rather than a third-party portal, and candidates should bookmark the exact page now instead of searching for it again once the key is live.

1. Visit upsc.gov.in and open the Exams tab.
2. Look for the Combined Medical Services Exam 2026 answer key link once posted.
3. Select Paper 1 or Paper 2 separately, since each opens as its own PDF.
4. Download and save both files rather than relying on a screenshot or a coaching platform's copy.

UPSC CMS 2026 Marks Calculation From the Answer Key

CMS applies the same penalty to a wrong answer in both papers, so the calculation method does not change between General Medicine and Preventive and Social Medicine once the key is out.

1. Match each response against the correct option for that paper.
2. Give full marks for every correct answer.
3. Take away one third of a mark for every incorrect answer, and nothing for a question left blank.

Paper 1 and Paper 2 are calculated the same way but kept separate, since a candidate must clear the minimum qualifying mark in each paper individually rather than on a combined total. A strong Paper 1 score cannot make up for falling short of the cutoff in Paper 2.

UPSC CMS 2026 Answer Key: Details Candidates Often Miss

A few points about this cycle sit outside the main sections above but still shape how a candidate should read their own score once the key is out, particularly around what is provisional and what is not.

• The provisional key is not final. UPSC can and does correct individual questions after reviewing QPRep representations, so an early self-assessed score can shift.
• Marks from the written papers are not shared publicly the way the answer key is. Only the qualifying result and, later, the final scorecard are released.
• Both papers are held on the same day with a gap between sessions, so a strong morning paper does not carry any advantage into how the afternoon paper is evaluated.

UPSC CMS 2026's answer key had not been posted as of the day after the exam, but the reform behind it is already confirmed policy, not a rumour. Candidates should watch upsc.gov.in directly over the coming days, keep the QPRep no-fee objection route in mind, and treat the NDA, CDS, and CSE Prelims 2026 timelines as the best available guide until CMS gets its own confirmed date.
