─── Factors to Consider ───
1. Interest: You will study 300+ hours for this; genuine interest is essential
2. Availability of material: Books, notes, coaching available?
3. Overlap with GS: More overlap = less total effort
4. Syllabus size: Smaller syllabus = easier to complete and revise
5. Scoring potential: Some optionals historically score better
6. Your background: Graduation subject can help
7. Previous year trend: Check success rates of your shortlisted optionals
─── Decision Process ───
Step 1: Shortlist 3-4 optionals based on interest and background
Step 2: Read the complete syllabus of each (available on upsc.gov.in)

Step 5: Check success rates and topper recommendations
Step 6: Make final choice within 1-2 months of starting preparation
