The Special Branch of the Bihar Police is one of the most respected intelligence and security units in the state. Being selected as a Special Branch Constable offers you a secure government job, regular salary increments as per the state pay scales, and the opportunity to carry out distinguished field duties.
Yet, hundreds of thousands of applicants do not understand how the CSBC selects candidates for this position. They spend all their time concerned about Paper 1.
Paper 1 is merely a qualifying language screening test. You only need to secure 30% in Paper 1 to have your answer sheet evaluated. The marks you obtain in Paper 1 are not included in your final selection score.
Your final selection, district assignment, and appointment letter all depend entirely on Paper 2.
Paper 2 consists of 100 marks divided into three sections: General Studies (50 marks), Mathematics (30 marks), and Bihar Special GK (20 marks).
Using our Bihar Police Special Branch Paper 2 mock test 2027 series helps you become proficient in this merit-based paper. You gain the ability to handle arithmetic calculations at the 10th standard level, master the history and geography specific to Bihar, and develop the speed necessary to achieve 75 or more marks on your OMR sheet.

| Contribution to Final Rank | None (the marks are not counted in the merit list) | Complete (the final selection list is entirely based on Paper 2) |
| Preparation Mindset | Basic grammar and speed | Maximum accuracy, numerical speed, and in-depth knowledge of state-related topics |

Full Syllabus Breakdown: The Three Pillars of Paper 2
In order to achieve a top score in Paper 2, your preparation must include all three areas of the syllabus:
1. General Studies (50 Marks / 50 Questions)
This forms the main section of Paper 2 and tests your knowledge of a variety of basic academic subjects:
- Ancient civilizations, the Mauryan and Gupta empires, medieval administration, the Revolt of 1857, the social reform movements, and the Gandhian phase of the freedom struggle.

2. Mathematics (30 marks for 30 questions)
The mathematics portion is in accordance with the syllabus set out for the 10th (Matriculation) standard; since arithmetic questions have definite numerical answers, well-disciplined candidates are able to obtain 27 or more marks out of 30:
- The number system and the basic rules of calculation include prime numbers, divisibility rules, fractions, decimals, square roots, and the BODMAS rule for the order of calculation.

3. Bihar Special General Knowledge (20 marks / 20 questions)
In this section the candidates from Bihar are differentiated from those who are unprepared, and all of the questions deal with the state's heritage, resources and governance:
- The ancient and medieval period of Bihar included the Magadha Empire, Pataliputra, Rajgir, the Nalanda and Vikramshila universities, as well as the teachings of Gautama Buddha and Lord Mahavira.
- Bihar's involvement in the struggle for independence included Babu Veer Kunwar Singh and the revolt of 1857 in Jagdishpur, the Champaran Satyagraha in 1917, the Kisan Sabha movement headed by Swami Sahajanand Saraswati, and the Quit India movement in Bihar in 1942 (among them the militants who were shot at the Secretariat).
- The geography of Bihar includes the Ganga river system together with its tributaries on both the north and south sides (such as the Gandak, Ghaghara, Kosi, Son, Bagmati, Punpun, and Falgu), the seasonal flood plains, the drought-prone areas in south Bihar, and the forested regions in West Champaran and Kaimur.

Previous Year Question (PYQ) Trend Analysis
An analysis of the trends in the previous CSBC police examination questions shows the clear distribution across the 100 questions of Paper 2:
| Question Style Category | Share in 100 Questions | What the Questions Test | Recommended Student Strategy |
|---|---|---|---|
| Direct Factual Recall | 50 Questions. | These include direct historical dates, constitutional articles, scientific units, district facts, and capital cities. | Start with these and provide your answers within 40 minutes without working them out on scratch paper. |
| Arithmetic Calculations | Thirty Questions | These are math problems set out step by step and cover topics such as profit and loss, percentages, ratios, work and time, and speed. | Over a period of 50 minutes, work through these problems systematically, using clear and well-organized scratch paper. |
| Applied Concepts & Regional GK | The 20 Questions | include multi-statement questions on history, details regarding the river tributaries of Bihar, and indicators from the economic survey. | Try them in the next 20 minutes and use 10 minutes to check your OMR bubbles. |
Category-Wise Cutoff Trends: The 75+ Target Rule
The high level of competition for the cutoff scores in the CSBC Special Branch recruitment is due to the fact that Paper 2 is the one factor which determines the final merit list.
Do not mix up the qualifying criteria with the final selection marks; the government has fixed a minimum qualifying percentage ranging from 30% to 40%. In reality, though, those candidates who have just met the qualifying limit are eliminated when the merit list is being prepared.
Refer to the historical score patterns and the safe target benchmarks listed below:
| Candidate Category | Minimum Qualifying Benchmark | Expected Written Cutoff (out of 100) | Final Recommended Safe Target Score |
|---|---|---|---|
| Unreserved / General (UR Male) | 40% (40 Marks) | 74 – 78 Marks | 80+ Marks |
| Unreserved / General (UR Female) | 32% (32 Marks) | 65 – 69 Marks | 72+ Marks |
| Economically Weaker Section (EWS) | 40% (40 Marks) | 68 – 72 Marks | 75+ Marks |
| Backward Class (BC Male) | 36.5% (36.5 Marks) | 71 – 75 Marks | 78+ Marks |
| Extremely Backward Class (EBC Male) | 34% (34 Marks) | 67 – 71 Marks | 74+ Marks |
| Scheduled Caste (SC Male & Female) | 32% (32 Marks) | 60 – 64 Marks | 68+ Marks |
| Scheduled Tribe (ST Male & Female) | 32% (32 Marks) | 62 – 66 Marks | 70+ Marks |
| Wards of Freedom Fighters (WFF) | 32% (32 Marks) | 56 – 60 Marks | 65+ Marks |
Rule on Strategic Preparation: You must always try to obtain between 78 and 82 marks in your full-length practice tests since scoring in that range ensures you have a safe margin regardless of how the rest of the candidates perform.

15 Common Mistakes Aspirants Make in Bihar Police Special Branch Paper 2
Avoid these common preparation errors to protect your score:
- Wasting Time on Paper 1 Topics During Paper 2 Prep: Spending hours on Hindi and English grammar while preparing for Paper 2, which contains only GS, Math, and Bihar GK.
- Ignoring the 30 Marks of Mathematics: Assuming you can clear the exam on General Studies alone. Mathematics makes up nearly a third of the paper and is essential for a competitive score.
- Leaving Questions Blank on the OMR Sheet: Leaving bubbles empty when there is zero negative marking. Always attempt all 100 questions.
- Neglecting Bihar Specific Geography: Failing to study local river systems, district boundaries, and soil types, missing easy marks in the 20-mark Bihar GK section.
- Doing Messy Rough Calculations: Writing numbers haphazardly in narrow margins, leading to calculation slips on basic arithmetic questions.
- Failing to Practice on Paper OMR Sheets: Practicing only on computer screens and struggling to fill 100 paper bubbles accurately during the timed exam.
- Getting Stuck on Difficult Math Questions: Spending 4 minutes trying to solve one tricky compound interest problem while 10 easy General Studies questions remain unread.
- Forgetting Basic Unit Conversions: Forgetting to convert speeds from kilometers per hour to meters per second ($km/h \times \frac{5}{18}$) in train problems.
- Studying National History Without Bihar's Role: Memorizing national freedom struggle events while forgetting key state movements, like the Champaran Satyagraha and the Kisan Sabha.
- Studying Without a Countdown Timer: Practicing without a strict 120-minute timer, resulting in rushed calculations during the final minutes of the exam.
- Memorizing Math Formulas Without Problem Practice: Memorizing formulas without solving practical numerical problems on scratch paper.
- Filling Two Bubbles for One Question: Accidental double-bubbling cancels your mark for that question, even if one choice is correct.
- Overlooking the General Science Section: Ignoring basic physics and biology questions from 9th and 10th NCERT textbooks.
- Assuming Minimum Qualifying Marks Guarantee Selection: Believing that scoring 40 marks will get you appointed, when final selection requires 75+ marks.
- Neglecting Physical Fitness During Written Prep: Spending months studying while failing to build the running stamina needed for the physical test.
