The written examination carries 500 marks and includes two papers of 250 marks each. Both papers contain 120 objective questions and must be completed within two hours.

| Paediatrics | 24 | 50 |
| Total | 120 | 250 |
General Medicine includes cardiology, respiratory medicine, gastroenterology, neurology, endocrinology, haematology, infectious diseases, dermatology, psychiatry, emergency medicine and toxicology. Paediatrics covers neonatology, childhood emergencies, developmental milestones, immunisation, nutrition and common childhood diseases.
Paper 2 covers Surgery, Gynaecology and Obstetrics, and Preventive and Social Medicine.
| Subject | Questions | Approximate Official Distribution |
|---|---|---|
| Surgery | 40 | 33.33% |
| Gynaecology and Obstetrics | 40 | 33.33% |
| Preventive and Social Medicine | 40 | 33.33% |
| Total | 120 | 100% |
The Surgery portion may include General Surgery, ENT, Ophthalmology, Orthopaedics, Traumatology and Anaesthesiology. Preventive and Social Medicine includes epidemiology, biostatistics, health programmes, nutrition, environmental health and communicable and non-communicable diseases.
Previous UPSC CMS papers indicate that the overall difficulty level generally ranges from moderate to difficult. The examination has gradually shifted from straightforward factual questions to clinical scenarios, integrated concepts and multiple-statement questions.
Paper 1 usually requires strong clinical understanding because many questions present symptoms, investigation findings or treatment situations. Candidates must identify the diagnosis, appropriate investigation, possible complication or suitable line of management rather than simply recall a definition.
Paper 2 is generally moderate but covers a wider range of subjects. Surgery and Obstetrics questions frequently involve clinical decision-making, while Preventive and Social Medicine tests epidemiological concepts, health programmes, screening, biostatistics and public-health applications.
Analysis of papers from 2020 to 2025 shows that multiple-statement questions increased from about 18% in 2020 to more than half of the paper in some later years. Around 48% to 53% of questions in recent papers have followed a multiple-statement format, making conceptual accuracy and option elimination increasingly important.
| Paper or Subject | Previous-Year Difficulty |
|---|---|
| General Medicine | Moderate to Difficult |
| Paediatrics | Moderate |
| Surgery | Moderate |
| Gynaecology and Obstetrics | Moderate |
| Preventive and Social Medicine | Moderate to Difficult |
| Overall | Moderate to Difficult |
Clinical scenario-based questions generally take more time than direct factual questions. Candidates therefore need to balance speed with accuracy, especially because negative marking applies.
The official scheme broadly defines the subjects covered in each paper. However, manual classification of the actual questions shows that effective subject weightage has varied across different years, particularly in 2024 and 2025.
| Year | General Medicine | Paediatrics |
|---|---|---|
| 2020 | 96 | 24 |
| 2021 | 91 | 29 |
| 2022 | 94 | 26 |
| 2023 | 93 | 27 |
| 2024 | 82 | 38 |
| 2025 | 84 | 36 |
General Medicine remained the dominant subject in all six years. However, the share of Paediatrics increased considerably in 2024 and 2025, moving from approximately one-fifth of Paper 1 to nearly one-third.
| Year | Surgery | Obstetrics and Gynaecology | Preventive and Social Medicine |
|---|---|---|---|
| 2020 | 40 | 41 | 39 |
| 2021 | 40 | 40 | 40 |
| 2022 | 40 | 40 | 40 |
| 2023 | 40 | 40 | 40 |
| 2024 | 40 | 30 | 50 |
| 2025 | 34 | 34 | 52 |
Paper 2 maintained an almost equal subject distribution between 2020 and 2023. However, Preventive and Social Medicine received higher effective weightage in 2024 and 2025, accounting for more than 40% of the questions in those papers.
These figures are based on subject-wise classification of previous question papers and should not be treated as a fixed distribution for UPSC CMS 2026. Integrated questions may also cover concepts from more than one medical discipline.
Frequently tested General Medicine areas include:
In Paediatrics, candidates should prioritise neonatal care, paediatric emergencies, immunisation, growth and development, nutrition and common childhood infections.
Cardiology, pulmonology and infectious diseases were among the most prominent Paper 1 areas in the 2024 and 2025 papers, while gastroenterology and endocrinology had higher representation during 2021–2023.
Important Surgery topics include General Surgery, gastrointestinal surgery, trauma, orthopaedics, pre-operative and post-operative management, anaesthesia, ENT and Ophthalmology. General Surgery and abdominal or gastrointestinal conditions have repeatedly contributed a substantial number of questions.
Candidates should focus on antenatal care, high-risk pregnancy, labour management, obstetric emergencies, postpartum complications, menstrual disorders, infertility, contraception and gynaecological malignancies. Obstetrics has received greater attention than Gynaecology in several recent papers.
Important PSM areas include:
The recent increase in PSM weightage makes it an important scoring area for UPSC CMS 2026 preparation.
Each question carries approximately 2.08 marks. One-third of the marks assigned to a question will be deducted for an incorrect answer. Selecting more than one option will also be treated as incorrect, even when one of the selected options is correct. No penalty is applied to an unanswered question.
Candidates can estimate their marks using the following method:
Estimated marks = Marks obtained from correct answers – Negative marks for incorrect answers
The score calculated using an unofficial answer key will remain provisional until UPSC publishes the official answer key.
