Syllabus questions

UPSC CSE Syllabus 2026 FAQ

What is the difference between Prelims and Mains syllabus?

The Prelims syllabus is broader and tests general awareness, while the Mains syllabus is more in-depth and analytical. Mains requires a deeper understanding of specific subjects and their interlinkages.

Are the qualifying papers in Mains counted for the final rank?

No, the marks obtained in the two language papers are not counted for the final merit list. They are only qualifying in nature, and candidates must score a minimum percentage to be considered for evaluation.

How many optional subjects can I choose for the Mains exam?

Candidates must choose only one optional subject for the Mains examination. The syllabus for this subject is detailed and requires dedicated preparation.
