Quick answer: UPSC prelims tests breadth across polity, history, geography, economy, environment, science and current affairs. Beginners fail by starting with too many sources. Start small and build.
Pattern
- GS Paper 1: 100 questions, 200 marks, −0.66 per wrong; decides the cut-off.
- CSAT (Paper 2): 80 questions, qualifying at 33%; comprehension, reasoning, basic maths.
Step 1: NCERT base (months 1–3)
- History: Class 6–12 (old NCERTs for ancient/medieval)
- Geography: Class 6–12
- Polity: Class 9–12
- Economy: Class 9–12
- Science and environment: Class 6–10 science, Class 12 biology last unit
Step 2: Standard books (months 4–8)
| Subject | Book |
|---|---|
| Polity | M. Laxmikanth |
| Modern history | Spectrum |
| Geography | G.C. Leong + atlas |
| Economy | Ramesh Singh or Sriram notes |
| Environment | Shankar IAS |
| Art and culture | Nitin Singhania |
Step 3: Current affairs + tests (months 6–12)
- One newspaper daily (The Hindu / Indian Express) — 45 minutes, note only what links to the syllabus.
- A monthly current affairs magazine for revision.
- Previous 10 years’ prelims papers — solve topic-wise.
- Test series from month 8; one test a week, 3-hour analysis.
Daily routine (6–8 hours)
- Newspaper 45 min; static subject 3 h; revision 1 h; CSAT 30 min (3 times a week); answer-writing basics for mains 30 min
Beginner rules
- One source per subject; revise it 3 times.
- Do not buy ‘compilations’ in the first six months.
- Keep a doubt list; clear conceptual doubts (economy, polity articles) the same week.
Common mistakes
- Ignoring CSAT until the last month
- Reading the whole newspaper instead of syllabus-linked news
- Collecting notes without revising
