Choosing the right optional subject is one of the most critical decisions in your UPSC 2027 journey. In a recent topper talk, Utkarsh (AIR 32) shared the exact reasons why he chose Geography—offering a brilliant blueprint for how you should select your own optional subject to maximize your scores.
If you want to clear the civil services exam, your optional subject should satisfy three major criteria.

Contents
1. Natural Familiarity and Background
For Utkarsh, Geography ran in the family—his grandfather studied it in the 1970s and his father is a Geography lecturer. While you don’t need a family legacy, having some baseline familiarity or a prior academic background in a subject can give you a massive head start for UPSC 2027. It reduces the initial friction of learning complex syllabus topics from scratch.
2. Real-World Curiosity and Observation
A great optional subject should address your natural curiosity. Utkarsh notes that as someone who loves traveling and stepping outside, Geography perfectly explained the phenomena he observed in the real world:
- Understanding why an Aurora happens.
- Observing how a glacier wall moves downwards and identifying the tongue of a glacier.
- Spending hours naturally engaging with a globe or an atlas.
When your UPSC 2027 optional matches your real-world observations, studying stops feeling like a chore and becomes an engaging process.
3. The “Comfort Food” Rule
This is the ultimate test for your UPSC 2027 preparation. Utkarsh explicitly states that your optional subject must feel like your “comfort food.”
“Optional is something that you should be very comfortable with… If I don’t want to study anything, I would love to study geography anytime.”
Your optional accounts for 500 marks in the mains exam. If it is a subject you can happily pick up even when you are exhausted or completely burnt out from general studies, you have found the right fit.
The Verdict for UPSC 2027 Aspirants
Do not pick an optional subject solely based on popular trends or what others claim is “high scoring.” Look for a subject where you have a bit of familiarity, genuine curiosity, and a deep level of personal comfort. If a subject passes these three tests, it is the right vehicle to carry you to success in UPSC 2027.
