After analysing 16 years of UPSC Prelims papers (2010–2025) in a fully data-driven manner, Margdarshan IAS has built a scientific map of what the exam truly demands. Every single question was broken down subject-wise, year-wise, topic-wise, and then consolidated into 423 Themes and 1,555 Microthemes—the most accurate representation of UPSC’s core blueprint.

This chart clearly shows how many themes each subject contributes: Polity and History dominate with the highest thematic load, while areas like Social Issues and Reports & Indices have fewer but highly scoring micro-areas. This helps aspirants understand how much depth each subject needs, where to allocate more time, and which segments deliver maximum output with focused study.
