Bihar Police Constable Syllabus 2026: Written Exam Topics and Study Plan

Quick answer

The Bihar constable written test, run by the Central Selection Board of Constables (CSBC), tests general knowledge, reasoning, numerical ability and Hindi, with a focus on Bihar. We could not verify the 2026 section split, the marks or the negative marking from the official notice in this session. Treat the topic list below as a study guide, and check the notice for each drive before you rely on any number.

What the written test usually covers

• General knowledge: Bihar history, geography, culture and politics, plus Indian polity, economy and science at school level.
• Current affairs: National and state news from the last year, especially government schemes and appointments.
• Reasoning: Series, analogies, coding and decoding, blood relations, direction sense and puzzles.
• Numerical ability: Arithmetic, percentages, ratio, profit and loss, time and work, and data from tables.
• Hindi: Grammar, vocabulary, comprehension and error spotting.

Why the notice matters more than this guide

The sections, the number of questions, the time and the penalty can change between drives. Earlier CSBC drives had different rules for the constable and operator posts. Use the notice of the drive you want, and do not rely on a summary for the marks.

Bihar-specific topics to revise

• The major events and leaders of Bihar's history, from ancient to modern times.
• Geography of Bihar: rivers, districts, agriculture and the main industries.
• Bihar culture, festivals and the state's famous places.
• State government schemes, recent appointments and the state's budget basics.

How to read a constable notice

Start with the eligibility section, then the exam scheme, then the physical standards, then the document list. The exam scheme tells you the sections, the number of questions and the marks. The physical standards tell you what to train for. The document list tells you what to gather before the form opens. Read all four before you start studying, so your plan matches the drive.

Common reading mistakes

Candidates often plan from an old notice, or from a summary that copied last year's figures. Check the notice date and the drive name before you start. If the notice you read is not the current one, your practice may not match the real exam.

A four-week study plan

• Week 1: Read the notice and the syllabus. List the topics and mark the weak ones.
• Week 2: Reasoning and numerical ability, with 30 questions a day and a review of every wrong answer.
• Week 3: General knowledge of Bihar and India, with a daily read of a reliable newspaper.
• Week 4: Hindi grammar and comprehension, plus one timed mock each week.

Physical and document rules

Constable posts may have a physical test. Standards for running and body measurement are set in the notice, and they can exclude a candidate before the written result counts. Start training early, and keep your domicile and category certificates ready.

Common mistakes

• Using an old syllabus. Check the notice for the drive.
• Ignoring Bihar-specific questions. They are a regular part of the paper.
• Skipping the physical training. It can cut candidates early.

How to revise Bihar-specific content

Build a one-page sheet for Bihar: key dates in state history, the major rivers and districts, the state's main crops and industries, the state capital and its regions, and the leaders and reformers whose names recur in exams. Update the sheet from the state's official publications and a reliable newspaper, and revise it weekly.

How to revise reasoning and numerical ability

Use a timed set each day. Start with the basic methods: percentages, ratios, averages and simple interest for numerical ability, and series, analogies and coding for reasoning. Mark each question you got wrong, and write the method for it in one line. Review these lines before every new set.

Hindi section

Revise the common grammar rules, idioms and synonyms. Read a short passage each day and answer two questions. Check the answers and note the reason for each correct option, which builds the habit of spotting the right answer quickly.

Mock tests and time management

Take a timed mock once a week in the last month. Give yourself the exact time in the notice. After each mock, sort the mistakes into knowledge gaps, misreads and time losses. Work on the group with the most mistakes first.

Reading the notice before you study

Before you start, read the notice for the drive and write down four things: the sections, the number of questions in each, the total marks and the penalty rule. Then set your practice to match. A drive with a penalty needs a different guessing rule from one without, and a drive with a physical test needs training to start early.

Current affairs: a monthly habit

Keep a monthly list of national and state events with dates, names and places. Focus on government schemes, appointments, sports results and state-level decisions. Revise the list every weekend and test yourself with five questions. Current affairs questions often come from the last six months, so a monthly list is enough.

Hindi section: daily practice

Read a short Hindi passage each day and answer two questions. Revise grammar in short bursts: one rule a day, with three examples. Keep a list of word pairs and idioms that you mix up, and review it each week.

Reasoning and numerical ability: a daily set

Solve one timed set of 20 questions each day, mixing reasoning and numerical ability. Review every wrong answer, and write the method in one line. Keep these lines in a notebook and read them before each new set.

Physical preparation

If the drive has a physical test, start training at least eight weeks before the test, and keep a log of your timings. Check the standards in the notice and build your training around them. Rest days and sleep matter as much as the training itself.

Questions candidates ask most

Is the syllabus the same every drive? Usually close, but the notice decides. Check each one.

Can I prepare before the notice? Yes, for the general topics. Wait for the notice before you pay for a course or a mock series.
