PSIR – Political Science and International Relations

Using PSIR notes from

Every PSIR paper has its own way of studying and understanding that will help you to make best use of available time. Under every section (i.e. 1A, 1B, 2A, 2B) we’ve discussed in detail the way syllabus can be covered. But we also want to suggest that there is no hard & fast rule when it comes to political science. It always boils down to what suits you. We are presenting notes, go ahead, read them, think about them, initiate/participate in discussions, do writing practice & ace the exam.

We have tried our best to provide comprehensive notes. And especially for Paper 1A & 2A, we don’t think anything else is required. For the rest of the part, everyone needs to remain updated with current developments in international politics. And by proper study of theoretical part, you will get maturity to decide what is important and what is not not, in contemporary world politics.

Answering PSIR Questions.

Most important thing while answering questions is, the interpretation of question. Half battle is won in understanding questions properly. Unless you understand what is being asked, there is every chance of writing something else, which may be connected to topic, well written, but not worthy of marks.

Answer language should be simple in communication. But not at the cost of discipline jargons like proliferation, deterrence, security dilemma etc. A golden rule to study Political Science and International Relations (PSIR) is to read less and think more. Have independent thinking, try to see the relevance of ideas mentioned, historical, contemporary examples to assist/question the theories, potential flaws in the ideas proposed etc. You can also comment your opinions below each post and engage in healthy debate and discussion. When we express ourselves, it helps us to strengthen our own concepts & get rid of wrong notions we develop. 

In Political Science, we don’t have proofs like sciences. So we have to back up our answers with examples & logic. Our answers should be logically coherent and convincing to the reader.

Initially there is no need to remember things, important concepts should be understood. From second revision onwards try to remember things. After 3-4-5 revisions, entire material can be zipped to 20-30 pages. This will reduce revision time drastically.

For those who are from science/technical background, don’t rush. Since one is unaware of fundamentals & ‘technical’ words of the subject, one may not understand everything. But 2nd reading onwards things make sense like never before. So have little patience.

It is also important that, throughout preparation, one sticks to the syllabus provided by UPSC. Many students develop academic interest in the discipline and get diverted from UPSC preparation. You can download PSIR optional syllabus from link given below.


It’s a long journey which will not only tests your intelligence but also your patience & determination. So always remain enthusiastic. Best of luck for your studies.
