Introduction: Why Your Optional Subject Choice Matters
In the highly competitive landscape of UPSC Civil Services Examination, your choice of optional subject can be the decisive factor between success and failure. While General Studies papers test your breadth of knowledge, the optional subject demonstrates your depth of understanding in a specialized field. Students frequently research the best optional subjects for the UPSC Mains exam, often looking for those with high success rates and syllabus overlap with the General Studies papers.
The optional subject carries 500 marks (250 marks × 2 papers) out of the total 1750 marks in the Mains examination, representing nearly 29% of your total score. This significant weightage makes it crucial to choose wisely and prepare strategically.
