Bihar Board Class 10 Grading System 2027: Grade Band, Marking Scheme and Division Criteria

What Is the Bihar Board Class 10 Marking System?

The Bihar Board Class 10 (Matric) examination is scored out of 500 marks across five main subjects, with each subject carrying 100 marks. Your division and percentage are calculated on these five subjects, so the total that matters for your result is 500.

You may also appear in an additional (optional) subject. This sixth subject does not add to the 500-mark total, but it provides a betterment route — if you fail one main subject yet pass the additional one, the additional subject can replace it, allowing you to qualify without losing a year.

Within each 100-mark subject, marks are divided between a written theory paper and, where applicable, a practical or internal-assessment component. Science subjects carry an 80-mark theory paper and a 20-mark practical; language and social-science subjects are assessed largely through the written paper. Your subject score is the combined total of these components out of 100.

How Does the Bihar Board Class 10 Grading System Work?

BSEB places your marks in each subject into a fixed letter-grade band. The grade scale is absolute — a grade depends only on the marks you score, not on how other students perform. A score of 90% and above always earns an A1, regardless of the year or the difficulty of the paper.

The table below shows the grade bands BSEB uses for each 100-mark subject, along with the grade point and remark for each band. These boundaries are established policy and apply to the 2027 cycle exactly as they did in previous years.

The grade is shown alongside your numerical marks on the marksheet; it does not replace them. Bihar Board reports actual marks, the division and the subject grade together, so colleges and recruiters can read your exact score.

To see how these bands play out in practice, the 2026 cycle provides the most recent benchmark. In 2026, 15,10,928 students appeared and 12,35,743 passed, for an overall pass rate of 81.79%. By division, 4,43,723 students secured First Division, 4,75,511 Second Division and 3,03,103 Third Division. Pushpanjali Kumari and Sabrin Parveen jointly topped with 492 marks (98.4%), placing them firmly in the A1 band. The 2027 cycle results will be available in April 2027.

How Are Grade Points, CGPA and Percentage Calculated?

Bihar Board Class 10 does not issue a single CGPA the way CBSE does. Instead, your result is built around actual marks, a division and a subject-wise grade. There is no averaging of grade points into one cumulative figure that then gets multiplied by a conversion factor.

Your percentage is read straight from your marks using a simple formula.

Percentage = (Total marks obtained in 5 main subjects ÷ 500) × 100

For example, if you score 410 out of 500, your percentage is (410 ÷ 500) × 100 = 82%, placing you in First Division. Because BSEB already prints your percentage and division, you do not need any CGPA-to-percentage conversion factor.

If you want a quick indication of your performance quality, you can average the grade points from the grade band table. An average grade point of 8 reflects consistent A2-level work across subjects; an average near 9 signals A1-level marks throughout. Treat this as a personal indicator only — your official standing is the division and marks on the marksheet, not an averaged grade point.

What Are the Pass Criteria and Division System?

To be declared passed in Bihar Board Class 10, you must clear two conditions simultaneously. You need a minimum of 30 marks (30%) in every individual subject and a minimum of 150 marks in aggregate out of 500. Falling short of 30 in even one subject means you have not passed that subject, even if your total crosses 150.

Once you pass, your aggregate marks decide your division, as shown in the table below.

If you fail in one or two subjects, you are not failed outright — you become eligible for the Bihar Board compartment (supplementary) examination. In the 2026 cycle, compartment exams were held from 2 to 6 May 2026, and the compartment result was declared on 23 May 2026. For 2027, compartment dates have not yet been announced; they are expected to follow a similar schedule in May–June 2027 after the main result. Clearing the compartment lets you complete Class 10 in the same academic year without losing a full year.

What Is the Bihar Board Grace Marks Policy?

BSEB awards grace marks to help students who fall just short of passing. If you are short of the pass mark in a limited number of subjects by a small margin, the board may add grace marks so you can be declared passed. The exact number added is capped and is decided by the board each year after result tabulation — grace marks are not guaranteed.

A long-standing provision protects strong overall performers. If you score at least 75% in aggregate but fail in only one subject by not more than 10% of that subject’s marks, you are declared passed, and your division is fixed on your actual marks. Grace marks are applied to push a borderline student over the pass line, never to change a division already earned.

Absolute vs Relative Grading: How Is BSEB Different?

Bihar Board uses absolute grading, while some boards use relative or position-based grading. In absolute grading, your grade is tied only to your own marks — the A1 band is the same 90%-and-above range every year. In relative grading, grade boundaries shift each year depending on cohort performance, so the same score can earn different grades in different years.

This predictability is the practical advantage of the Bihar Board system — you can read the grade table before the result and know exactly what marks you need for each band and division. If you score 74 in a subject, you will receive a B1 grade (70–79 band) regardless of how the rest of Bihar performed.
