  • Start Essay writing — one essay every 10 days
  • Revise all static subjects covered in Month 1–5

🎯 Month 9–10: Prelims Sprint

  • Attempt full-length mock tests every alternate day
  • Analyze mistakes — do not repeat the same error twice
  • Revise current affairs from DCA+ monthly compendium
  • CSAT: Ensure 33% marks — practice comprehension and data interpretation daily

  • Revise all notes — GS I, II, III, IV in 3 weeks
  • Finalize Essay approach — practice 2 full essays per week
  • Revise important schemes, committees, reports for GS II and III

🎙️ Month 12: Interview Preparation

  • Fill DAF (Detailed Application Form) carefully — it is your interview script
  • Practice mock interviews with AIR X Mentorship panel
  • Read current events from last 6 months thoroughly
  • Prepare answers on: hometown, graduation subject, hobbies, national issues
  • Stay calm — the board tests your overall personality, not just knowledge

💡 Key Takeaway from Aman Sharma

"UPSC is a marathon, not a sprint. Consistency beats intensity every single time. 2 hours of focused study daily for 12 months beats 10-hour cramming sessions. Stick to the plan, trust the process, and revise, revise, revise."
