Bihar Board Question Types 2027

Knowing the exact format of each section helps you allocate your 3 hours 15 minutes efficiently. This can help you avoid losing marks through poor time management.
Bihar Board Exam Pattern: Question Types and Marking Scheme
The Bihar Board exam pattern divides questions into three main sections plus a separate practical session. Each section has a fixed format and marking scheme.
| Question Type | Section | Format | Marks | Internal Choice? |
|---|---|---|---|---|
| MCQ — Objective | Section A | Single correct answer from 4 options; marked on OMR sheet | 1 mark each | Yes — attempt 50 out of 60 (or 35 out of 42) |
| Short Answer | Section B | 2–3 sentence responses; tests direct recall and concept clarity | 2 marks each | Yes — attempt 15 out of 25–30 |
| Long Answer | Section C | Detailed explanations, derivations, essays, or case-based answers | 4–5 marks each | Yes — attempt 4–5 out of 6–8 |
| Practical / Viva | Separate Session | Lab experiments, observations, record book, and viva questions | 20–30 marks | N/A |
MCQ Marking Rules
MCQs in Section A are answered on an OMR sheet using a black or blue ball-point pen. The scanner cannot read corrected bubbles, so overwriting or correction fluid is not allowed.
Bihar Board does not use a separate pencil-fill OMR sheet. Responses go directly on the main answer sheet.
Short Answer Guidelines
Each short answer should be 30–50 words. Use subject-specific keywords to earn full marks.
The marker awards 2 marks based on key points, not word count. Lengthy explanations are not needed.
Long Answer Marking
Bihar Board uses step-wise marking for long answers. In Mathematics, every correct step carries marks even if the final answer is wrong.
In Science, labeled diagrams carry separate marks. Always include them where relevant.
Competency-Based Questions
BSEB introduced competency-based questions in Class 10 in 2025. These test application and analysis rather than rote recall.
These questions appear within the existing sections. They do not change the overall marks or format.
Practical Exam Rules
Practical exams are conducted separately in January 2027 before the theory exams begin. Practical marks count toward the final result and the passing threshold.
Missing the practical exam can result in failing the subject.
Bihar Board Exam Pattern: Changes in 2027 vs Previous Year

How to Prepare Based on Bihar Board Exam Pattern
Your preparation for Bihar Board 2027 should map directly to the exam structure. The 50-50 MCQ-subjective split means equal time and effort must go into both formats.
Students who only practice MCQs or only write long answers consistently underperform in one half of every paper.
Bihar Board Exam Preparation Tips 2027
Practice MCQs from Model Papers
BSEB releases official model question papers for both Class 10 and Class 12. Solving these is the most direct preparation for Section A.
The MCQ pool tends to draw from a predictable set of topics. Identify these repeat areas and focus there first.
Attempt All MCQs Without Skipping
Bihar Board has no negative marking. Every unattempted MCQ is a guaranteed zero, while a guess gives you a 25% chance of earning +1 mark.
In a 50-MCQ section, even 10 educated guesses can add several marks to your total. Never leave an MCQ blank.
Build Keyword-Based Answers for Section B
Short-answer questions carry 2 marks and reward precision over length. Study the key terms and definitions for every chapter.
Practice writing 2–3 sentence answers that include the subject's standard terminology. These answers are marked by subject teachers who look for keywords.
Use Step-Wise Writing for Section C
Long-answer questions (4–5 marks) in Bihar Board follow step-wise marking. In Mathematics, write every step of a calculation, even obvious ones — each carries marks.
In Science and Social Science, structure your answer with a brief introduction, main points, and a conclusion.
Prepare Practicals Before December 2026
Practical exams for Bihar Board 2027 are expected in January 2027. Complete all required experiments and maintain your lab notebook.
Revise the theory behind each experiment for the viva. Practical marks directly contribute to your subject total and to the passing threshold.
Plan Your Reading Time (15 Minutes)
Bihar Board gives 15 minutes to read the question paper before the 3-hour writing window begins. Use this time to scan all three sections.
Identify which optional MCQs, short answers, and long answers you will attempt, and circle them. Deciding during the exam wastes writing time.
Focus on Choice Strategy
You never attempt every question in a Bihar Board paper. In Section A you skip 10 MCQs (or 7 for practical subjects), in Section B you skip 10–15 short-answer questions, and in Section C you skip 3–4 long-answer questions.
Know your strongest topics per section before exam day so your choices are made from preparation, not panic.

Internal Choice in Bihar Board 2027
Yes, Bihar Board 2027 provides internal choice in all three sections. In Section A, you attempt only 50 out of 60 MCQs (or 35 out of 42).
In Sections B and C, you choose how many short and long answers to write from a larger pool. This lets you skip topics you are less confident about.
Step-wise Marking in Bihar Board 2027
Step-wise marking means the examiner awards marks for each correct step in a long-answer solution, even if the final answer is wrong. This applies to Mathematics derivations and Science numerical problems.
Writing all your working clearly earns you partial credit even when you make a calculation error at the end.
