How to Prepare for Bihar Police SI Exam 2026?
A successful preparation strategy does not require studying every subject for several hours every day. What matters is consistency and proper revision.
1. Start With the Syllabus
Before opening your books, divide the syllabus into different sections:
- General Knowledge
- Current Affairs
- Hindi
- Science
- History
- Geography
- Civics
- Mathematics
- Reasoning
Then identify your strong and weak areas.
2. Give Special Attention to Bihar GK
For a state-level police examination, Bihar-specific knowledge deserves special attention.
Prepare:
- Bihar History
- Bihar Geography
- Bihar Economy
- Bihar Culture
- Important Personalities
- Rivers
- Important Places
- Bihar Current Affairs
3. Read Current Affairs Every Day
Instead of collecting months of Current Affairs at the end, spend some time every day.
Make short notes for important:
- Events
- Appointments
- Awards
- Schemes
- Sports
- Defence developments
- Science and technology news
4. Practise Mathematics Daily
Mathematics improves through practice. Even 30–45 minutes of daily question-solving can make a noticeable difference over time.
5. Strengthen Hindi Grammar
Revise grammar topics regularly and solve practice questions after every topic.
6. Practise Reasoning
Reasoning should be approached through questions rather than theory alone. Start with basic problems and gradually increase the difficulty.
7. Solve Previous-Year Questions
Previous-year questions help you understand the type and level of questions generally asked and also show which topics require more attention.
8. Take Mock Tests
Start with sectional tests and later move to full-length papers.
After each mock test, analyse:
- Wrong answers
- Questions taking too much time
- Calculation errors
- Guesswork
- Weak subjects
This analysis is often more useful than simply taking another mock test.
9. Do Not Ignore Physical Fitness
Keep physical training alongside written preparation. Waiting until the written examination is over can create unnecessary pressure.
