Cover Ancient India, Medieval India, Modern India, the national movement, world history and Indian art and culture. Prelims requires factual clarity and chronology, while Mains requires causes, consequences, comparisons, historical debates and well-chosen examples.

Start with prehistory and ancient India, continue to early medieval and medieval India, then study European entry, colonial expansion, reform and the freedom struggle. Study world history after you understand the transition to modern states, and integrate art and culture with the relevant period.

NCERT textbooks provide the foundation, but they are not the entire preparation. Add syllabus-focused topic notes, standard references where necessary, maps, timelines and previous-year questions. History Optional requires substantially greater depth than General Studies.

Revise through short tables on sites, sources, chronology, terms, religions, dynasties and art forms. Practise statement-based questions and keep an error log. Avoid memorising isolated facts without knowing the period and context.

Organise notes around colonial policies, economic change, social reform, resistance and phases of nationalism. For every major event, prepare background, causes, participation, methods, limitations, consequences and historical significance.

World History focuses on processes such as industrialisation, revolutions, nationalism, imperialism, world wars, decolonisation and political ideologies. Modern Indian History centres on colonial rule, Indian responses and the national movement, though the two frequently intersect.

Convert long reading into timelines, comparison tables, maps and theme sheets. Keep one core page per topic and add only evidence that improves an answer or helps eliminate a Prelims option.

Use spaced revision. Revisit a topic within a few days, again after two to three weeks, and once more during test revision. The exact interval can vary, but active recall and question practice are more useful than repeated passive reading.
