Quick Info
| Detail | Information |
|---|---|
| Exam | Bihar Police Sub-Inspector (Daroga) |
| Papers | Prelims (GK) + Mains Paper 1 (Hindi) + Mains Paper 2 (GS) |
| Total Books Needed | 8-10 maximum |

Golden Rule - Pehle Ye Samjho
3 books achhe se padho, 10 books skim karne se behtar hai. Bihar SI ka exam NCERT level GK + Bihar-specific knowledge maangta hai - research-level depth nahi chahiye. Targeted study = smart study.
1. General Knowledge (Prelims + Mains Paper 2)
GK sabse heavy weightage wala subject hai (dono papers mein):
| Book | Author/Publisher | Why Recommended | Price (approx) |
|---|---|---|---|
| Lucent's General Knowledge | Lucent Publications | Bihar exams ka "Bible" - 80% GK topics cover ho jaate hain | Rs 300-350 |
| NCERT Class 6-12 (History, Geography, Civics, Science) | NCERT | Foundation books - free PDF download available | FREE (ncert.nic.in) |
| Bihar GK (Unique Publications) | Dr. Manish Rajan / Unique | Bihar-specific history, geography, culture - MUST for Bihar SI | Rs 200-250 |
Priority: NCERT first (foundation) → Lucent GK (exam-oriented) → Bihar GK (Bihar-specific questions)
2. Bihar Specific GK (CRITICAL - 15-20% paper)
Bihar GK se har paper mein 15-20 questions aate hain. Generic books mein ye cover nahi hota:
| Book | Author/Publisher | Coverage | Price |
|---|---|---|---|
| Bihar: Ek Parichay (Bihar: An Introduction) | Crown Publications | Bihar districts, rivers, festivals, schemes, famous personalities | Rs 150-200 |
| Bihar Samanya Gyan | Upkar Publications | Bihar history, culture, agriculture, census data | Rs 150-200 |
| Bihar GK (Unique Publications) | Dr. Manish Rajan | Comprehensive Bihar-specific GK | Rs 200-250 |
Tip: Inme se koi ek lo, teeno nahi chahiye. Content overlap 70% hai. Bihar GK (Unique) sabse comprehensive maani jaati hai.
Free alternative: "Bihar GK" search karo YouTube pe - kaafi channels full Bihar GK cover karte hain for free.
3. Indian History (Ancient, Medieval, Modern)
History se Prelims mein 12-15 questions + Mains mein bhi aata hai:
| Book | Author | Best For | Price |
|---|---|---|---|
| NCERT History (Class 6-12) | NCERT | Foundation - ancient to modern India | FREE |
| Lucent GK (History Chapter) | Lucent | Quick revision, one-liner format | Included in Lucent |
| Spectrum: A Brief History of Modern India | Rajiv Ahir | Modern Indian history (freedom struggle) | Rs 250-300 |
Priority: NCERT (Class 6, 7, 8, 12 - History) + Lucent History chapter = 90% syllabus done. Spectrum sirf extra depth ke liye hai.
4. Indian Polity & Constitution
Polity se 10-12 questions consistently aate hain:
| Book | Author | Best For | Price |
|---|---|---|---|
| NCERT Civics (Class 9-12) | NCERT | Basic concepts - Parliament, fundamental rights, DPSP | FREE |
| Indian Polity (M. Laxmikanth) | M. Laxmikanth (Summary version) | Comprehensive but detailed - selected chapters padhein | Rs 400-500 |
| Lucent GK (Polity Chapter) | Lucent | Quick revision for exam | Included in Lucent |
Warning: Laxmikanth poori mat padhna - Bihar SI ke liye selected chapters (Parts 1-4) kaafi hain. BPSC ke liye poori padhni padti hai, SI ke liye nahi.
5. General Science (Physics, Chemistry, Biology)
Science se 10-15 questions Prelims mein aate hain (mostly 10th level):
| Book | Author | Best For | Price |
|---|---|---|---|
| NCERT Science (Class 9-10) | NCERT | Basic physics, chemistry, biology concepts | FREE |
| Lucent's General Science | Lucent Publications | Exam-focused science one-liners | Rs 200-250 |
Strategy: NCERT Class 9-10 Science achhe se padho + Lucent Science chapter revise karo. Advanced science (Class 11-12 level) nahi aata Bihar SI mein.
6. Mathematics & Reasoning
Math + Reasoning milake 15-18 questions aate hain:
| Book | Author | Best For | Price |
|---|---|---|---|
| RS Aggarwal - Quantitative Aptitude | RS Aggarwal | Number system, percentage, ratio, profit-loss, SI/CI | Rs 350-400 |
| RS Aggarwal - Verbal & Non-Verbal Reasoning | RS Aggarwal | Series, analogy, coding-decoding, puzzles | Rs 300-350 |
| NCERT Math (Class 9-10) | NCERT | Basic arithmetic concepts | FREE |
Tip: RS Aggarwal poori mat karo. Bihar SI ke liye selected chapters kaafi hain:
- Math: Number System, Percentage, Ratio, Average, Profit-Loss, SI/CI, Time-Speed-Distance
- Reasoning: Series, Analogy, Coding-Decoding, Venn Diagrams, Blood Relations, Direction Sense
7. Hindi (Mains Paper 1 - Qualifying)
Hindi Paper qualifying hai (30% chahiye), lekin fail hone ka risk bhi hai:
| Book | Author | Best For | Price |
|---|---|---|---|
| Vastunishtth Hindi (Objective Hindi) | Dr. Hardev Bahri | Grammar, Sandhi, Samas, Muhavare, Vilom | Rs 200-250 |
| Hindi Grammar (Lucent) | Lucent | Quick revision of Hindi grammar | Included in Lucent |
Reality: Agar tumhari Hindi school level se achhi hai toh sirf grammar sections padho (Sandhi, Samas, Alankar, Ras, Chhand). Comprehension practice PYQ papers se karo.
8. Current Affairs (Prelims + Mains)
Current Affairs se 10-12 questions aate hain (last 6-8 months):
| Resource | Type | Cost |
|---|---|---|
| Pratiyogita Darpan Monthly Magazine | Monthly magazine (Hindi) | Rs 50/issue |
| Drishti IAS - Monthly Current Affairs PDF | Free PDF download | FREE |
| YouTube Channels (Study IQ, Khan Sir, Crazy GK Trick) | Video format | FREE |
| Bihar Current Affairs (any compilation) | Bihar-specific current affairs | Rs 100-150 |
Strategy: Last 6 months ka current affairs cover karo. National + Bihar dono important hain. Daily 15 min newspaper + monthly compilation = sufficient.
9. Practice Sets & Solved Papers
PYQ + Mock tests se final polish hoti hai:
| Book | Author/Publisher | Content | Price |
|---|---|---|---|
| BPSSC Bihar Daroga Solved Papers (Kiran) | Kiran Institute | 2008 se 2026 tak solved papers | Rs 250-300 |

Scam Warning
Books ke naam pe bhi fraud hota hai:
- "Guaranteed selection book - Rs 5,000" - Koi book selection guarantee nahi de sakti
- "Leaked question bank" - Fake (exam computer-based hai)
- "Coaching ke original notes Rs 2,000" - Mostly low quality photocopies
- Telegram pe "complete material pack Rs 500" - Pirated + outdated content
Yaad rakho: Rs 1,500 mein sab achhi books aa jaati hain + NCERT free hai. Zyada paisa kharcha karne ki zaroorat nahi. Scam Alerts dekho.
FAQs
Q: Sirf Lucent GK se selection ho sakta hai? A: Lucent se Prelims clear ho sakta hai, lekin Mains Paper 2 ke liye Bihar GK + Current Affairs + RS Aggarwal bhi chahiye. Lucent alone = 60-70% syllabus.
Q: NCERT kis class tak padhnni chahiye? A: History: Class 6, 7, 8, 12. Science: Class 9-10. Civics: Class 9-12. Geography: Class 6, 9-10. Sab free PDFs ncert.nic.in pe hain.
Q: Kya coaching zaroori hai? A: Nahi. Self-study + YouTube + books se clear ho sakta hai. Coaching sirf guidance ke liye helpful hai, mandatory nahi. Budget tight hai toh self-study + free resources = sufficient.
Q: RS Aggarwal poori karni padegi? A: Nahi. Selected chapters karo: Number System, Percentage, Ratio, Average, SI/CI (Math), aur Series, Analogy, Coding-Decoding, Venn Diagrams (Reasoning). Poori book ka 40% kaafi hai.
Q: Hindi Paper 1 ke liye special book chahiye? A: Agar Hindi medium se padhai ki hai toh grammar section (Sandhi, Samas, Alankar, Muhavare, Vilom) revise karo + 2-3 PYQ papers solve karo. Alag se heavy preparation nahi chahiye - ye qualifying paper hai.
Q: Current Affairs kab se padhni chahiye? A: Exam se 6-8 months pehle se. Agar exam April 2026 mein hai toh August 2025 se March 2026 ka current affairs padho. Monthly magazine (Pratiyogita Darpan) ya free PDFs (Drishti IAS) use karo.
Q: Online books (PDF) ya physical books - kya better hai? A: Physical books for main study (marking, notes, revision easy). PDF for NCERT aur reference (free + portable). Dono mix karo.
Q: Kitne months ka time chahiye preparation ke liye? A: Minimum 3-4 months dedicated study (6-8 hours daily). Agar working hai toh 6 months lagao (3-4 hours daily). Quality of study matters more than hours.
