Perfect - I have everything I need. Here is your complete 3-week battle plan for UPSC CMS 2026 (exam: August 2, 2026).
UPSC CMS 2026 - 3 Week Cracker Plan
(6-8 hrs/day | Exam: August 2, 2026)
EXAM STRUCTURE (Know This Cold)
| Paper | Subjects | Marks | Questions |
|---|
| Paper 1 | General Medicine + allied (Derma, Psychiatry, Pharma) + Paediatrics | 250 | 96 Medicine + 24 Paeds = 120 |
| Paper 2 | Surgery (+ ENT, Ophtha, Ortho, Anaesthesia) + OBG + PSM | 250 | ~40 each = 120 |
Negative marking: -1/3 for wrong answers
No negative marking if you leave it blank - use wisely.

WHAT TO DO WITH PYQs
- Don't just read Q+A - read the explanation for EVERY option
- Mark topics that repeat - if a topic appears in 3+ PYQ years, it WILL come again
- Note the distractors - CMS often uses similar-sounding wrong options
- Negative marking strategy - attempt only when you can eliminate at least 2 options confidently
QUICK TIPS FOR EXAM DAY
- Paper 1 is tougher (Medicine is harder to score) - don't panic
- Attempt PSM and Paediatrics first in Paper 2 (easiest, fastest marks)
- In surgery, anatomy/signs questions are easy marks - don't skip
- If stuck between 2 options after 1 minute, mark and move on - revisit at end
- Target: 75-80 correct in each paper (out of 120) to be safe
This plan covers all subjects systematically. If you follow it consistently for 21 days at 6-8 hours/day, you will cover the entire high-yield syllabus with PYQ integration and revision built in. Good luck - you have 3 solid weeks and that is enough!
