In 2025, 9.38 lakh people applied for the Civil Services Examination and 5.77 lakh appeared. Around 14,000 clear Prelims. The exam rewards elimination skill and calm more than memory.
The ten tips
- 1. Read the official syllabus and the last 10 years of question papers first. They tell you what UPSC asks; nothing else does.
- 2. NCERTs (Class 6–12) for History, Geography, Polity, Economy and Science are the base. Read them once fully, then only the chapters that keep appearing.
- 3. One standard book per subject: Laxmikanth (Polity), Spectrum (Modern History), GC Leong or NCERT (Geography), the Economic Survey summary (Economy). Do not switch books mid-way.
- 4. Current affairs: one source, read daily, revised monthly. Cover the 12 months before the exam, with extra attention to government schemes, environment, and science.
- 5. CSAT is qualifying (33%) but it fails thousands every year. Solve one CSAT paper a week from January; comprehension and basic maths are enough.
- 6. Negative marking is one-third of a question. Attempt a question only when you can eliminate two options with reason. Blind guesses lose marks over a full paper.
- 7. Take at least 25 full-length mocks. Sit for them at 9:30 AM, on paper, with an OMR sheet. The exam is physical as well as mental.
- 8. Keep an error notebook. Every wrong answer gets one line: the fact you missed and why you chose the wrong option.
- 9. Revise more than you read. A good ratio is three revisions for every first reading. Use short notes, not long ones.
- 10. Protect the last 30 days: no new books, no new sources, no new topics. Revision and mocks only.
A realistic timeline
June to December: foundation reading and NCERTs. January to March: standard books plus current affairs revision. April to the exam: mocks, PYQs and revision. Mains preparation should run alongside until about 90 days before Prelims.
