BharatNotes History: Class 6–8 Our Pasts + Class 11–12 Themes (supplement Mughals from old NCERT/TN board after the 2025 revisions). Geography: Class 9–12 (all four senior books are gold). Polity: Class 9–11 Democratic Politics & Indian Constitution at Work. Economy: Class 11 Indian Economic Development + Class 12 Macroeconomics (skip Microeconomics). Science: Class 6–10 selective. Class 11 is the single most important NCERT year.
The class-wise map you actually need
Most candidates either read all NCERTs from Class 1 (waste) or skip them entirely (disaster). Here is the subject-to-class mapping verified against the latest UPSC syllabus and the post-2025 NCERT curriculum revisions (the medieval-history shake-up matters).
History
| Class | Book | Why it matters |
|---|---|---|
| Class 6 | Our Pasts I (now retitled Exploring Society: India and Beyond in some 2025 prints) | Ancient India basics — Harappa, Vedic, Mauryas |
| Class 7 | Our Pasts II | Medieval India — but 2025 revision trimmed Delhi Sultanate; cross-check with old PDF on archive.org |
| Class 8 | Our Pasts III | Modern India introduction — colonialism foundations |
| Class 11 | Themes in World History | Industrial Revolution, World Wars, Cold War — high ROI for GS-1 World History |
| Class 12 | Themes in Indian History I, II, III | Harappa, Bhakti-Sufi, Mughals, Colonialism, Partition (the most exam-relevant set) |
Skip Class 9 and 10 history NCERTs — Class 8 + Spectrum cover that ground better.
Critical 2025 update: The new NCERT Class 7 and 8 textbooks (released April 2025) have substantially trimmed Mughal-era content. Aditya Srivastava (AIR 1, 2023) prepared on the old NCERTs (pre-2023 prints) — that set remains the gold standard for UPSC. Buy the old prints from second-hand sellers or download free at archive.org. Supplement with Satish Chandra's Medieval India (NCERT old edition) for Sultanate and Mughal depth.
Geography (the four senior books are non-negotiable)
- Class 9: Contemporary India I
- Class 10: Contemporary India II — resources, agriculture, manufacturing, transport (Prelims goldmine)
- Class 11: Fundamentals of Physical Geography (the single most quoted NCERT in Prelims Geography) + India: Physical Environment
- Class 12: Fundamentals of Human Geography + India: People and Economy
G.C. Leong's Certificate Physical and Human Geography (Oxford) sits on top of Class 11 NCERT — read NCERT first, Leong second.
Polity & Governance
- Class 9: Democratic Politics I
- Class 10: Democratic Politics II
- Class 11: Indian Constitution at Work — the most important Polity NCERT. Read this before touching Laxmikanth.
- Class 12: Politics in India Since Independence + Contemporary World Politics (the IR primer for GS-2)
Economy
- Class 11: Indian Economic Development — planning, poverty, employment, infrastructure basics
- Class 12: Introductory Macroeconomics — GDP, money, banking, BoP (Anudeep Durishetty explicitly named this as an essential)
Skip Class 12 Introductory Microeconomics — it is not in the UPSC syllabus and consumes time you do not have.
Science & Tech
Class 6–10 Science NCERTs selectively:
- Class 9 Biology — Cell, Tissues, Diseases
- Class 10 Biology — Life Processes, Heredity
- Class 10 Chemistry — Periodic Table, Carbon Compounds (Prelims occasionally tests)
- Class 9–10 Physics — Light, Sound, Electricity basics
Do not read Class 11–12 PCM — diminishing returns.
Sociology / Society (GS-1)
- Class 11 Understanding Society + Class 12 Indian Society and Social Change and Development in India* — directly maps to GS-1 "Salient features of Indian society, diversity".
Mentor's class-priority ladder
If you have time for nothing else, prioritise Class 11 across all subjects. It is the single most analytical NCERT year and the closest to UPSC's expected reasoning depth. The hierarchy: Class 11 > Class 12 > Class 9–10 > Class 6–8.
Worked time allocation
A candidate with 8 weeks to cover all NCERTs from zero should split: 3 weeks (Class 6–10, including selective Science) + 3 weeks (Class 11) + 2 weeks (Class 12) + 1 buffer week for revision and PYQ tagging.
