Quick Info

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):

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:

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:

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:

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):

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:

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:

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):

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:

Free alternative: Bihar SI PYQ Download Guide - Testbook, Adda247, PW pe sab free available hain.

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.
