TBSE Class 10 Maths Compartment 2026: Chapter-Wise Weightage and High-Score Topics

The TBSE Class 10 Mathematics Compartment 2026 exam is scheduled for June 28, 2026. Algebra is the single heaviest unit with approximately 20 out of 80 theory marks, making it the top priority for compartment students.

Students who failed the TBSE Class 10 Mathematics exam in the main 2026 board results get a second chance through the compartment exam. The theory paper is 80 marks and internal assessment carries 20 marks, totalling 100 marks. You need at least 33 marks to clear the subject. A smart chapter-wise study plan — focused on the highest-weightage chapters — is the fastest route to clearing the compartment paper.

• The TBSE Class 10 Maths paper has six sections (A to F) totalling 80 marks; internal assessment adds 20 marks for a grand total of 100.
• Algebra (Polynomials, Linear Equations, Quadratic Equations, Arithmetic Progressions) carries approximately 20 marks — the largest single unit.
• Geometry (Triangles, Circles, Constructions) carries approximately 15 marks; Triangles alone is the most predictable chapter for proof-based long answers.
• Statistics and Probability together carry around 11 marks and are among the most scoring chapters because questions follow a fixed pattern.
• Students who master Algebra, Geometry and Trigonometry can realistically secure 47 or more marks out of 80, comfortably above the 33-mark passing threshold.

TBSE Class 10 Maths Compartment 2026 Paper Pattern

The TBSE Class 10 Mathematics compartment exam follows the same structure as the main board exam. The paper has six sections (A to F) with different question types and marks per question. Knowing the structure helps you manage time and attempt the right sections first.

The exam duration is 3 hours 15 minutes. You need a minimum of 33 marks out of 100 to pass the Mathematics compartment exam. Internal assessment marks from the main exam cycle are carried forward.

Chapter-Wise Marks Distribution in TBSE Class 10 Maths 2026

TBSE Class 10 Mathematics follows the NCERT curriculum divided into seven units. The table below shows the expected marks each unit carries based on the official curriculum structure and previous year paper patterns.

Algebra and Geometry together account for 35 marks — nearly 44% of the entire theory paper. Prioritising these two units is the most efficient strategy for compartment students with limited preparation time.

High-Score Topics to Prioritise in TBSE Class 10 Maths Compartment 2026

Some chapters deliver more marks and have more predictable question patterns than others. The table below ranks the chapters by their scoring potential for compartment students, based on previous year paper trends.

Compartment students who fully prepare the seven chapters above can realistically score 40–55 marks out of 80, which is well above the 33-mark passing threshold. Focus on these chapters before moving to lower-weightage topics like Coordinate Geometry or Probability.

Chapter-Wise Preparation Tips for TBSE Class 10 Maths Compartment 2026

Here is a chapter-by-chapter strategy for the TBSE Class 10 Maths Compartment 2026 exam. Spend the most time on chapters ranked 1 to 4 in the priority table above.

Real Numbers: Learn Euclid’s Division Lemma and the Fundamental Theorem of Arithmetic. Practice HCF and LCM using prime factorisation. This chapter almost always appears in Sections A and B as 1-mark questions — easy marks if you revise the two main algorithms.

Polynomials: Focus on the relationship between zeros and coefficients for quadratic and cubic polynomials. Division algorithm problems appear in Section C or D. Memorise the sum-of-zeros and product-of-zeros formulas.

Pair of Linear Equations in Two Variables: Practice all three methods — substitution, elimination and cross-multiplication. Word problems that translate into two equations are common in Sections E and F. Identify which method is fastest for each question type.

Quadratic Equations: Master factorisation and the quadratic formula. Know how to find the nature of roots using the discriminant (b² – 4ac). These questions appear across Sections C, D and E and carry 3–4 marks each.

Arithmetic Progressions: The nth term formula (a + (n–1)d) and the sum formula (n/2 × (2a + (n–1)d)) together solve almost every AP question. Practice word problems involving sums and the number of terms.

Triangles: Write out the proofs for the Basic Proportionality Theorem and the Pythagoras Theorem from memory at least three times before the exam. Long-answer proof questions in Section E or F are full marks if you follow the correct proof structure.

Coordinate Geometry: Keep a formula card with the distance formula, section formula and midpoint formula. Questions in this chapter are purely formula-driven — revising the three formulas for 30 minutes is enough for most students.

Introduction to Trigonometry: Memorise all trigonometric ratios and the three standard identities. Problems based on sin²θ + cos²θ = 1 and its rearrangements appear in multiple sections. For Applications of Trigonometry, draw a diagram before writing the solution.

Mensuration: Know the formulas for cylinder, cone, sphere, hemisphere and frustum. Combination-of-solids problems ask you to add or subtract volumes and surface areas — these questions follow the same structure every year and carry 4–5 marks.

Statistics: Practice mean by three methods (direct, assumed mean and step deviation). Median using the cumulative frequency formula and mode from a grouped frequency table are both regular long-answer topics. A single Statistics problem in Section E can fetch you 4 marks.

Probability: This is the lightest chapter in the syllabus. Revise the basic probability formula and practice coin, dice and playing card problems. Expect one question in Section A or B worth 1 mark — it takes less than 30 minutes to prepare fully.
