The WB Police Sub-Inspector exam is one of the most competitive in the state. Thousands apply. A few hundred get selected. The difference between rank 1 and rank 2001 is not intelligence: it is preparation quality. This guide gives you the strategy that works, drawn from what consistent top scorers do differently.
WB Police SI Exam 2026: Full Selection Process
The West Bengal Police Recruitment Board conducts the SI exam. The process has five stages:
- Stage 1: Preliminary Written Examination
- Stage 2: Physical Measurement Test (PMT)
- Stage 3: Physical Efficiency Test (PET)
- Stage 4: Final Written Examination
- Stage 5: Interview and Medical Examination
Check the WBPRB Recruitment hub for the current SI notification, application dates, and vacancy count.
SI Exam Eligibility 2026
- Education: Graduation from a recognized university
- Age: 20 to 27 years (general). SC/ST: up to 32 years. OBC-A/OBC-B: up to 30 years. Female: 3 additional years on all categories.

- Height (Female): Minimum 160 cm (155 cm for ST)
Preliminary Exam: What Toppers Do Differently
The SI preliminary paper has 200 questions. The syllabus looks broad but the actual question pattern is narrow. Here is where most marks concentrate:
- Bengali and English together: 50 questions
- General Knowledge (including West Bengal): 70 questions
- Arithmetic and Reasoning: 50 questions
- Elementary Science: 30 questions
Toppers score 75 percent or higher in GK. That is where the exam is won. Police exams weight West Bengal current affairs, law-and-order news, and state government schemes heavily. A general candidate who reads only national-level current affairs misses those questions entirely.
Subject-by-Subject Preparation Strategy
General Knowledge: The Core Differentiator
Read one Bengali newspaper every single day from the day you decide to appear for the SI exam. That is the non-negotiable foundation. Supplement with a monthly GK magazine. Keep a running notebook of WB-specific facts: police commissioners, important crime-related laws, state awards, and recent government schemes.
Know the Indian Penal Code sections that appear repeatedly in police exam GK: Section 302 (murder), 307 (attempt to murder), 376 (rape), 420 (cheating), 498A (domestic violence). Know which section applies to which crime. These are direct marks.
Arithmetic: Speed Is the Skill
The arithmetic section tests Class 10-level problems. Percentage, ratio and proportion, simple and compound interest, time-speed-distance, and profit-loss cover 80 percent of the questions. Practice 30 questions each morning for 8 weeks. By week 6, your calculation speed will be noticeably faster. Slow calculation under exam pressure costs you 10 to 15 marks.
Bengali Language
Grammar errors (sandhi, karak, samas), fill-in-the-blanks, and reading comprehension. The SI Bengali paper is harder than the constable level. Read one editorial per day from Anandabazar Patrika to build vocabulary and grammar intuition. Practice past SI Bengali question papers.
English Language
Focus on: error spotting, fill-in-the-blanks with appropriate prepositions or articles, and one-word substitution. Scoring 8 to 10 out of 15 is realistic with two weeks of focused practice. Use S.P. Bakshi’s Objective General English for targeted preparation.
Reasoning
Reasoning is fully learnable. Series completion, analogy, coding-decoding, and blood relations account for most reasoning questions in the SI exam. Practice 20 reasoning questions daily for 30 days. Most question types follow predictable patterns once you have seen them enough times.
