Bihar Board Class 10 Maths Syllabus 2027: Chapters & Easy Marks

A clear, honest guide to the BSEB Class 10 Maths syllabus — every chapter, how marks are split and which topics give you the easiest marks with little time left.
What is in the bihar board class 10 maths syllabus 2027?
If only a few months are left and you are still confused about what to study, take a breath — the bihar board class 10 maths syllabus is smaller and friendlier than it looks. BSEB Class 10 (Matric) Maths is a 100-mark paper (50 objective and 50 subjective) built on around 15 NCERT chapters, grouped into seven units: Number System, Algebra, Coordinate Geometry, Geometry, Trigonometry, Mensuration, and Statistics & Probability. You pass with 30 marks.
That means you do not need to master every corner of the book to clear the paper. You need the full chapter list in front of you, a clear idea of where the marks sit, and steady practice. I will give you all three below, step by step.
Before we start, keep the official source open in another tab. The 2027 pattern and exact weightage should always be confirmed from the Bihar School Examination Board official website — treat the numbers here as a planning guide, not the final word. When you are ready to test yourself, you can start with the free mock test and see where you stand today.
How many chapters are in BSEB Class 10 Maths?
The BSEB Class 10 Maths course follows the NCERT book, so you are looking at about 15 chapters. Do not panic at the number — many of them are short and share the same tricks. Here is the full list, grouped by unit so you can plan one unit at a time.
| Unit | Chapters |
|---|---|
| Number System | Real Numbers |
| Algebra | Polynomials; Pair of Linear Equations in Two Variables; Quadratic Equations; Arithmetic Progressions |
| Coordinate Geometry | Coordinate Geometry |
| Geometry | Triangles; Circles; Constructions |
| Trigonometry | Introduction to Trigonometry; Some Applications of Trigonometry |
| Mensuration | Areas Related to Circles; Surface Areas and Volumes |
| Statistics & Probability | Statistics; Probability |
What this means for you: study by unit, not by random chapter. If you finish Algebra fully, you have already covered the biggest block of marks. Keep the exact chapter list handy from the Bihar Board Class 10 (Matric) exam page as you tick each one off.
How are the marks distributed in the Maths paper?
The Maths paper is 100 marks — half objective (one-mark MCQs) and half subjective (short and long answers). The objective half is where careful students quietly collect marks, because one line of thinking gives you one full mark. The subjective half rewards neat, step-by-step working.
Here is an indicative unit-wise weightage based on the NCERT-aligned pattern. Confirm the final split for 2027 in the official notification before you lock your plan.
| Unit | Indicative marks (approx.) |
|---|---|
| Algebra | 22–25 |
| Geometry | 15–17 |
| Trigonometry | 12–14 |
| Statistics & Probability | 11–13 |
| Mensuration | 10–11 |
| Number System | 6–8 |
| Coordinate Geometry | 6–8 |
What this means for you: Algebra alone is nearly a quarter of the paper. If your time is short, give Algebra and Trigonometry your first and best hours. For the full subject-by-subject picture, the Bihar Board Matric 2027 subjects and marking scheme guide walks you through every paper, not just Maths.
Which chapters give you the easiest marks?
Every year, some chapters return the most marks for the least pain. These are formula-based or pattern-based, so once you learn the steps, the questions repeat in a predictable way.
- Real Numbers — HCF, LCM and prime factorisation. Short, scoring, and perfect for objective marks.
- Arithmetic Progressions (AP) — just two or three formulas. Practise 20 sums and you will rarely miss these.
- Statistics — mean, median, mode. Mechanical steps that give full subjective marks if you write them neatly.
- Probability — simple fraction answers. One of the fastest chapters to finish.
- Coordinate Geometry — distance and section formula. Plug in the values and the answer comes out.
- Introduction to Trigonometry — once the ratio table is memorised, many one-mark questions are almost free.
What this means for you: if you are a repeat candidate or studying alongside a job or housework, start here. These six chapters can carry you comfortably past the 30-mark pass line and give you confidence before you touch the harder word problems.
Two or three struggles — and one step for each
Let me name the problems I see most often, and give you one doable fix for each. No lectures, just the next step.
- "I forget formulas in the exam." Make one A4 sheet of all Maths formulas and read it for five minutes every morning. Repetition, not cramming, keeps them in your head.
- "I understand in class but freeze on new questions." That gap only closes with solving, not reading. Solve five fresh sums a day from a chapter you already studied.
- "I have very little time left." Follow the marks. Do Algebra, Trigonometry and the six easy chapters above first, and leave Constructions and the toughest Geometry proofs for last.
How should you practise with little time left?
Reading solved examples feels like studying, but the exam asks you to produce answers under a clock. The only way to build that is timed, chapter-wise practice with honest checking afterwards.
Work through one chapter, then take a short objective test on just that chapter and mark your mistakes. The Bihar Board Class 10 (Matric) All-In-One test series has 119 tests with full solutions in Hindi and English, so after each attempt you can see not only your score but why an answer was wrong. For a focused objective routine, the chapter-wise Matric mock test guide shows you how to build the habit.
And Maths is not your only paper. Once Maths feels steady, use the same method on Science — the Bihar Board Class 10 Science syllabus 2027 guide lists its chapters and marks the same way.
Your one step for today
Do not try to fix everything tonight. Just start with the free mock test, then mark the two or three topics where you lost the most marks. Tomorrow, open those chapters first. When you want full chapter-wise practice with solutions, the All-In-One test series is ready whenever you are. Steady, honest practice beats worry every single time.
