Political Science and International Relations (PSIR) is one of the optional subjects for the UPSC Civil Services Main Examination. Your optional takes up two of the nine mains papers, Paper VI and Paper VII, with 250 marks each, and both count towards your final rank along with the Essay and the four General Studies papers.
The CSE 2026 notice says the optional syllabi are "broadly of the honours degree level", which it explains as above a bachelor's degree and below a master's. Below are both PSIR papers exactly as the notice prints them, with a plain summary of how they are arranged and some pointers to help you decide.

Who this optional suits
Only you can weigh your interests, your background and the time you have. These pointers may help you think it through.
- Your degree. If you studied political science or international relations at college, much of Paper I's theory and Indian politics will be familiar.
- Reading thinkers. Paper I names thinkers and traditions, from Plato and Machiavelli to Gramsci, and from the Arthashastra to Sri Aurobindo and Ambedkar. If you enjoy reading ideas closely and comparing them, that part of the paper will play to your strengths.
- Following world affairs. Paper II includes contemporary global concerns and recent developments in India's foreign policy. It suits you if you already follow world affairs, and it means keeping your notes up to date through the year.
- Links with General Studies. Several PSIR topics are also named in the GS Paper II syllabus, such as the features of the Constitution, statutory bodies, India's relations with its neighbours, and international institutions. Prepare them once, with both papers in mind.
- Test it before you commit. Read the full syllabus above, then try answering a question or two from previous year papers. Choose on your own interest and background rather than on what others pick.
To compare PSIR with every other subject you could choose, see the full list of UPSC optional subjects and our note on how to choose an optional. For where the optional sits among the nine papers, see the UPSC Mains syllabus; for the related General Studies paper, see the GS Paper 2 syllabus and the guides to the polity and international relations syllabus.
