Phase 1 (Days 1–5): Foundation

Phase 2 (Days 6–12): Practice & Exposure
- Solve full-length past questions daily
- Focus on weak areas
- Practice logical reasoning consistently
- Begin timed sessions
Phase 3 (Days 13–18): Speed & Accuracy
- Attempt CBT-style mock tests
- Reduce time per question
- Avoid repeating mistakes
- Focus heavily on current affairs
Phase 4 (Final Days): Revision & Confidence
- Revise key topics
- Go through repeated questions
- Avoid learning new topics
- Stay mentally sharp
This structured approach ensures you’re not just reading—you’re improving daily.
DSS CBT Exam Day Strategy (What to Do Inside the Exam Hall)
Preparation alone is not enough. Your performance on exam day determines everything.
Before the Exam Starts

Build momentum early. This increases confidence and saves time. - Use the Skip Technique
