Shubhra Ranjan’s PSIR notes are the most asked-about study material in Political Science & International Relations optional. If you are here, you probably want to know what is in them, whether they are worth the money, and whether there is a free version. This page answers all three honestly.
What Shubhra Ranjan PSIR notes actually are
They are not a published book you can buy in a shop. They are the internal study material of Shubhra Ranjan IAS Study — produced for their classroom batches and their postal/correspondence programme, and supplied to enrolled students. That single fact explains most of what follows: there is no retail edition, no official PDF, and no legitimate free download.
What aspirants rate them for is consistency. The material is written to the PSIR syllabus unit by unit rather than assembled from general political science reading, and it is structured for answer writing — definitions, thinker positions and critiques arranged so they can be lifted into a Mains answer without re-processing.
Paper I coverage
- Political theory and its approaches; the major ideologies
- Western political thinkers, and Indian political thought
- The Indian Constitution, its making and its working
- Federalism, Panchayati Raj, and centre–state relations
- Political processes in India — parties, movements, pressure groups
Paper II coverage
- Comparative politics and comparative political analysis
- Theories of international relations
- India’s foreign policy, and India’s relations with major powers and neighbours
- International organisations, global institutions and their reform
- Security, nuclear policy, diaspora, and contemporary global issues
How to get the notes legitimately
There are exactly two honest routes.
1. Enrol with Shubhra Ranjan IAS Study
The classroom course, the online course and the postal/correspondence programme all include the notes. This is the only source that gives you the current material, updated for the present cycle. Check their official website for the batch schedule and fees, both of which change between cycles — we deliberately do not quote figures here, because outdated prices on third-party pages cause more confusion than they solve.
2. Buy a used printed set from a previous student
Reselling a physical copy you actually own is legal, and second-hand PSIR sets turn up regularly in aspirant groups and used-book marketplaces in Delhi. Two warnings. Check the year before you pay — a set more than two cycles old is badly out of date on Paper II. And a printed set is one person’s copy, not a licence to scan and redistribute it.
About the “free PDF” copies circulating online
Copies of these notes are uploaded to file-sharing sites and Telegram channels without permission. Three reasons, in order of how much they should matter to you.
- They are usually old. Most circulating sets are two to four cycles behind. In Paper I that is survivable. In Paper II it is actively harmful — a note on India’s foreign policy or on global institutions written three years ago will walk you into a wrong answer with confidence.
- They are usually incomplete. Scanned sets routinely drop modules, and you find out which ones in the exam hall rather than while preparing.
- They are someone’s work. A teacher wrote them and makes a living from them. You are preparing for a service built on public integrity; it is a strange place to start by taking something that was not given.
If the official notes are out of budget
This is the real situation for most aspirants, and it is worth saying plainly: you do not need any particular institute’s notes to score well in PSIR. Every year candidates clear with 300+ in the optional on self-study. What they have is not a specific set of notes but a complete stack.
What a PSIR self-study stack actually needs
- A theory base. Heywood for political theory and ideologies, O.P. Gauba for Indian coverage, and a reader on Indian political thought. These are in print and inexpensive.
- A current-affairs layer for Paper II. IR moves every month. A newspaper habit plus a monthly IR compilation does what no static note can.
- Topic-wise previous-year questions, so you study the syllabus in the shape UPSC actually asks it rather than the shape a textbook presents it.
- Model answers, because reading theory and writing a 20-mark answer under time pressure are different skills, and only the second one is marked.
The first two you can assemble yourself in a weekend. The last two are the ones aspirants never get round to building, and they are the ones that decide the score.
LotusArise PSIR Optional Notes — the legal alternative
Our own PSIR notes cover the full syllabus across both papers, written for answer writing rather than for reading. They are ours to give, so there is no grey area about downloading them, and they are current rather than a scan of something from three cycles ago.

The short answer
If you can afford Shubhra Ranjan’s course, the notes come with it and they are good. If you cannot, do not chase a three-year-old scan of them — build the stack above instead. The aspirants who score well in PSIR are not the ones with the best notes. They are the ones who wrote the most answers.
