Preparation Tips by Stage
For Prelims
Focus on accuracy. Every mark counts. Solve previous year papers, avoid guessing, and master time management. Build strong GS fundamentals; CSAT is mostly about practice and speed.
For Mains
Quality over quantity. Write balanced essays, structured GS answers. Focus on case studies for Ethics. Optional subject requires deep expertise. Write timed practice answers regularly.
For Interview
Be authentic. Know your DAF inside-out. Read current affairs. Practice mock interviews with experienced mentors. Confidence, clarity, and conviction matter more than perfect answers.
