What is the best optional subject for the UPSC mains?

Question

I am looking for a practical answer to this UPSC question: What is the best optional subject for the UPSC mains?

If someone has prepared seriously for this part of the UPSC process, please share a clear strategy, useful resources, and the mistakes that usually waste time. Honest advice from repeat aspirants would help a lot.

Ishita Bhonsle · Answer

Optional selection becomes much easier once you stop chasing trends and start checking interest, syllabus comfort, and material availability honestly.

That is usually where preparation starts feeling more manageable.

Shivam Fernandes · Answer

I would shortlist an optional only after checking:
- can I stay with this subject for a long cycle
- do the PYQs feel readable
- is there enough guidance and evaluation help
- does the subject suit my strengths

That small shift alone can save a lot of time.

High-scoring stories are not enough on their own. The same optional can work brilliantly for one student and feel exhausting for another.

Most people improve once that part becomes clear.

A few days with the syllabus and PYQs usually reveal more than hours of debate videos.
