Start with NCERT books (Class 6-12) for History, Geography, Polity, Economy, and Science foundation
Current affairs preparation must be daily — maintain a notes diary from newspapers and PIB for Prelims and Mains
CSAT (Paper 2) requires qualifying marks only — allocate 2-3 weeks dedicated preparation to clear the 33% threshold
Practice previous year UPSC Prelims papers under timed conditions — question pattern and difficulty remain consistent
