Time Breakdown: 120 Minutes#
120 questions, 120 minutes = 1 minute per question. But not all questions are equal.
The Two-Pass Method#
First pass (60 min): Scan all questions, answer easy ones first. Mark difficult ones for review. Target: 80-90 questions done.
Second pass (50 min): Return to the questions marked for review. Use elimination and educated guessing. Target: remaining 30-40 questions.
Buffer (10 min): Review anything still flagged and check that every question you meant to answer has a response.
Section-wise Strategy#
Paper I (General Medicine + Paediatrics): Typically longer clinical vignettes. Paper II (Surgery including ENT, Ophthalmology and Orthopaedics; OBG; PSM): Mix of direct and image-based questions. Adjust reading speed accordingly.
On-Screen (CBT) Tactics#
UPSC CMS is a computer-based test, so there is no OMR sheet and no answer-transfer step.
- Select each answer on screen as you go
- Use the review option for questions you want to revisit, rather than leaving them unanswered by accident
- Check the question palette before time runs out, so nothing you meant to answer is left blank
- Never change an answer unless you find a definite error in your reasoning
- Use the rough sheet for calculations

Frequently asked questions
How much time per question in UPSC CMS?
120 questions in 120 minutes = exactly 1 minute per question. However, image-based and long clinical vignettes may need 1.5 minutes, while one-liners need 30 seconds.
Should I attempt questions in order?
Many toppers recommend a two-pass approach: first pass for easy/medium questions (30-40 seconds each), second pass for difficult ones. This prevents getting stuck early.
Is there an OMR sheet in UPSC CMS?
No. UPSC CMS is a computer-based test: you select each answer on screen as you go, so there is no answer sheet to fill at the end. Use the on-screen review option for questions you want to revisit, and keep an eye on the timer.
