The UPSC syllabus for Political Science & International Relations is a dense two-page PDF. This page is that syllabus made teachable — and then made granular: the 40 chapters and 144 lessons we teach from at ALS IAS, followed by the complete topic-wise microlisting of the PSIR optional syllabus — every subtopic under every chapter, transcribed in full from the ALS IAS syllabus booklet (2027–28). The Complete PYQ Map hangs every question from this structure.

How the course moves through it. The Foundation Batch covers all 40 chapters in 115 three-hour sessions across roughly 24 weeks — Paper I-A first, then I-B, then II-A, then II-B. A previous-year question is discussed inside the lesson it belongs to, not in a separate PYQ class.

Where the marks actually fall — chapter weightage, 2011–2025

How to read it. Foundations of Democratic Governance, Party System & Social Movements, and India's Relations with Global Powers are the three heaviest chapters in the subject — together over 18% of all marks asked since 2011. A chapter "active" in 10+ of 15 years is a standing appointment, not a trend. This weight distribution is exactly why the course's session plan gives high-weight chapters their hours first — and why the microlisting below marks depth per subtopic.
