The 90-Day Practical Plan
If you have less than 90 days, compress the plan by increasing daily hours and merging early weeks.
Daily Time Budget (suggested)
- Working aspirants: 3–4 hours/day
- Full-time aspirants: 6–8 hours/day
- Suggested split: GS 60 min | Maths/Science 60 min | Reasoning 45 min | Hindi 30 min | Mock/PYQ 60 min | Revision 15–30 min
Weeks 1–2: Foundation
- Understand full syllabus & pattern. Pin a printed syllabus checklist.
- Build basics in Maths (percentages, ratio, averages) and Reasoning (series, analogy).
- Start Bihar GK file; add one news/event daily to current affairs notes.
Weeks 3–6: Core Building
- GS: Modern history, Polity, Economy basics, Geography (India + Bihar) and state schemes.
- Maths: SI/CI, time-work, time-distance, profit-loss, mensuration.
- Reasoning: Syllogism, blood relations, puzzles. Daily focused practice.
- Start taking one full Prelims mock every 10 days; analyze thoroughly.
Weeks 7–10: Speed & Accuracy
- Timed topic drills (e.g., 20 questions in 18 minutes).
- Target and fix weak areas from your error log.
- One full mock per week; focus on time management and OMR/CBT discipline.
Weeks 11–12: Final Sprint
- Alternate-day full mocks to simulate exam fatigue and pacing.
- No new topics—only revision of notes and past mistakes.
- Practice relaxation, sleep schedule, and light exercise for peak performance.
Test-Taking Strategy (Simple Rules)
- Two-pass approach: Pass 1 — attempt clear and easy questions across sections. Pass 2 — attempt moderate/hard flagged ones. Only guess if you can eliminate at least two options.
- Section order: Start with your strongest subject to build confidence; keep flexible.
- Accuracy over attempts: Prefer fewer, highly accurate attempts to many risky guesses.
- OMR/CBT hygiene: Fill answers steadily; avoid bunching at the end.
