📊 UPSC CMS 2026 Exam Pattern
The Combined Medical Services Examination is conducted in two stages.
📝 Written Examination – 500 Marks
🎤 Personality Test / Interview – 100 Marks
The written examination consists of two objective-type papers, each carrying 250 marks and lasting two hours. The questions are multiple choice questions (MCQs) and the paper is set only in English. Candidates must also remember that negative marking applies for wrong answers, which means guessing randomly can reduce your final score.
Paper 1 mainly focuses on General Medicine and Paediatrics, while Paper 2 evaluates knowledge in Surgery, Gynaecology & Obstetrics, and Preventive & Social Medicine.
Understanding the weightage of subjects allows candidates to allocate their preparation time more effectively.
