Introduction
Each year, lakhs of aspirants register and appear for the UPSC Civil Services Examination, for one single dream, that is to become an IAS, IPS or IFS officer. The prelims generally tests your knowledge and aptitude, and when it comes to the main examination your optional subjects often decide an aspirant’s final rank.
If you’re preparing for UPSC 2025, then knowing the UPSC optional subject list and how to select the right UPSC optional subject will help in your preparation immensely. In this blog, we will discuss the various subjects, how to select them, and what their significance means.
What is Optional in UPSC?
An optional subject is a paper you choose for the UPSC Mains exam. You will have to write two papers (Paper VI and Paper VII) on your chosen subject, carrying 250 marks each.

This makes the decision even more crucial. Your choice of IAS optional subjects must align with your strengths, background, and interest.
