In short: Bihar Board (BSEB) has 17 lakh+ students appearing for Class 10 annually. The exam follows a unique 50% MCQ format — the highest MCQ proportion among all Indian boards. Maths and Hindi are 100-mark papers (50 MCQ + 50 subjective), while Science and SST are 80 marks theory (40 MCQ + 40 subjective) + 20 marks practical. There is no negative marking in MCQs, so attempt all questions. The MCQ section alone is worth 50 marks in Maths — mastering it can secure a pass even with moderate subjective performance.

- Writing section (18 marks) follows fixed formats — memorise Patra Lekhan and Nibandh formats
- Comprehension (16 marks) requires no preparation beyond reading practice
- For Literature, read Godhuli Part 2 chapters thoroughly — MCQs come from text lines
English Chapter-Wise Weightage (100 Marks: 50 MCQ + 50 Subjective)

MCQ Strategy — The Bihar Board Advantage
Since 50 marks (or 40 marks for Science/SST) are MCQs with no negative marking, this is your biggest scoring opportunity.
MCQ Golden Rules:
| Rule | Explanation |
|---|---|
| Attempt ALL MCQs | No negative marking means every blank answer is a guaranteed zero. Even random guessing gives 25% accuracy (12-13 marks out of 50 for free). |
| Read all 4 options | Don't rush to mark the first option that looks correct. Elimination is more reliable than direct selection. |
| Eliminate 2 options first | If you can eliminate 2 wrong options, your chances jump from 25% to 50%. |
| Mark uncertain ones | On the OMR sheet, lightly mark uncertain answers. Come back during review time. |
| Don't change answers randomly | First instinct is usually correct. Only change if you find a concrete reason. |
| Time allocation | Spend maximum 30 minutes on MCQs (roughly 35 seconds per MCQ). Save more time for subjective. |
MCQ Subject-Wise Practice Plan:
| Subject | MCQs to Practice | Source |
|---|---|---|
| Maths | 500+ | Previous year papers + NCERT Exemplar |
| Science | 400+ | Previous year papers + NCERT back exercises |
| SST | 400+ | Previous year papers + NCERT one-liners |
| Hindi | 300+ | Previous year papers + Grammar exercises |
| English | 300+ | Previous year papers + Grammar exercises |
| Total | 1900+ |
Previous Year Pattern Analysis (2024-2026)

Frequently Asked Questions
How many students appear for Bihar Board Class 10?
Approximately 17 lakh+ (1.7 million) students appear for Bihar Board Class 10 annually. It is the third-largest board in India after UP Board and CBSE. The pass percentage has been around 80-85% in recent years.
Is there negative marking in Bihar Board MCQs?
No. There is absolutely no negative marking in Bihar Board MCQs. This means you should attempt every single MCQ — leaving any blank is throwing away potential marks. Even if you guess randomly, you have a 25% chance of being correct on each question.
How much can I score just from MCQs?
MCQs are worth 50 marks in Maths, Hindi, and English, and 40 marks in Science and SST. If you prepare well, you can score 35-45 out of 50 in MCQs. Combined across subjects, a student who is strong in MCQs can secure 175-225 marks out of the MCQ total of 230 marks. This alone is enough to pass comfortably.
What is the pass mark for Bihar Board Class 10?
You need 33% in each subject to pass. For a 100-mark subject, that is 33 marks. For Science and SST (80 theory + 20 practical), you need 33 out of 100 total (theory + practical combined). Most students who prepare systematically score well above the passing marks.
Is NCERT enough for Bihar Board?
Yes, NCERT is more than sufficient. Bihar Board follows NCERT textbooks, and 90% of questions come from NCERT. Do not waste money on unnecessary reference books. Complete NCERT, solve NCERT back exercises, and practice previous year papers — this covers everything you need.
Which subject is easiest to score in?
Hindi and Social Science are generally considered the easiest to score in because they are theory-heavy and follow predictable patterns. Grammar sections in both Hindi and English offer guaranteed marks with practice. Science and Maths require more conceptual understanding and practice.
How should I fill the OMR sheet?
Use only the pen specified in the exam instructions (usually black ballpoint). Fill the bubble completely — do not make tick marks or half-fill. Do not overwrite or use whitener. Double-check your roll number and question numbering. Practice filling a sample OMR sheet before the exam.
What happens if I fail in one subject?
If you fail in one or two subjects, you can appear in the Bihar Board supplementary examination (compartment exam), usually held in June-July. You do not need to repeat the entire exam. Focus on the failed subject specifically and improve your MCQ accuracy.
How do Bihar Board marks compare with CBSE for college admission?
Most colleges that accept Bihar Board students do not discriminate based on the board. For central universities (like DU), CUET scores matter more than board percentage. For Bihar state colleges, Bihar Board marks are directly used. Focus on scoring well rather than worrying about board comparisons.
