PSIR Optional for UPSC, taught the Rahul Puri way.

Political Science & International Relations — the optional with the deepest overlap into GS II and Essay, now taught in small batches from Old Rajinder Nagar by Rahul Puri, ex-Rau's IAS faculty of a decade. Answer-writing-first. Current-affairs-linked. Built to score.

II · Why PSIR

Why serious aspirants keep returning to PSIR.

~40% overlap with GS II & III.

Polity and Governance are already on your reading list for GS II. IR and India-and-the-world are GS II staples. Internal Security and Economic Development echo Paper 2 Section B. Nothing you learn for PSIR is wasted on Mains.

Essay paper, unlocked.

The Philosophy section of the essay paper (Liberty, Justice, Democracy, Nationalism) draws directly from PSIR Paper 1. Most aspirants scramble for quotes — PSIR students already have frameworks.

Current affairs linkage.

Every headline — a cabinet reshuffle, a G-20 summit, a Supreme Court judgment on federalism — is PSIR. Answer writing becomes analytical the moment you have the theoretical vocabulary.

Consistent, writeable scoring.

PSIR has been a 280–310 scorer for a decade. No fashion-cycle collapses like PubAd after 2013. Marks come from structure and argument, not one-line factual recall.

III · The faculty

Rahul Puri has been teaching PSIR in
Old Rajinder Nagar for over a decade.

Rahul Puri — PSIR faculty at Anantam IAS, ex-Rau's IAS

Rahul Puri sir taught PSIR at Rau's IAS for ten years before co-founding Anantam IAS as the flagship initiative of its ex-faculty. His approach is the opposite of what most UPSC aspirants expect from a political theory class — theory is not a syllabus to finish, it is a framework to argue with. Every Rawlsian paragraph links to a Supreme Court judgment, every Gramsci reference lands on yesterday's editorial.

IX · Rankers who wrote PSIR

The case study is the evidence.

All India Rank96

"For Polity and PSIR, just trust Rahul Sir and Vaibhav Sir. That was the whole strategy. I stopped collecting books after the third month. Class notes, answer writing, and two rounds of PYQ — that was it."

Alongside Kashish, Meghna Chakravarthy also wrote PSIR in CSE 2024 as an Anantam mentee. 2025 class PSIR students — Samiksha Dwivedi (AIR 56), Aniket Ranjan (AIR 48) and others — feature below with their rank badges.
