Preparation Strategy

We at Exam Bhai believe that self-study thrives on structure. Follow this three-phase roadmap:

• Phase 1 (Foundation): Spend the first three months mastering NCERT books (Class 6–10) for History, Geography, and Science. Focus on building a strong grip on Mathematics basics and English grammar.
• Phase 2 (Consolidation): Deep dive into standard reference books like M. Laxmikanth for Polity. Integrate daily newspaper reading for Current Affairs.
• Phase 3 (Execution): The final month should be dedicated solely to revision and solving at least 10 years of previous year question papers. Use this time to identify and eliminate your weak areas.

Cut-Off Trends

Official cut-off marks are released by the UPSC after the final results are declared on upsc.gov.in. Historically, the written cut-off for IMA has fluctuated between 120 and 145 marks, while OTA cut-offs usually range between 90 and 110. Remember, these trends are subject to paper difficulty and vacancy counts, so aim for a score 15–20 marks above the previous year's average to remain in the safe zone.
