Important Questions for HSC Math's 2026 (Science Stream) | PDF Guide

INTRODUCTION

Preparing for the Maharashtra HSC Board 2026 can feel like a high-stakes puzzle, especially for science stream students. Mathematics is often the "make or break" subject—it requires precision, speed, and a strategic approach to the syllabus. With the 2026 exams emphasizing competency-based questions, simply memorizing formulas won't be enough.

This guide provides a comprehensive list of HSC Math's Science important questions 2026, broken down by Part 1 and Part 2, along with the latest weightage data to help you prioritize your study sessions.

HSC Math's Science Important Questions 2026: Paper Pattern & Weightage

Before diving into the questions, you must understand the 80-20 pattern implemented by the MSBSHSE for 2026. The theory paper is worth 80 marks, while 20 marks are reserved for internal assessments and practical.

2026 Chapter-Wise Weightage (With Options)

Part 1: Algebra & Geometry	Marks	Part 2: Calculus & Statistics	Marks
Mathematical Logic	8	Differentiation	9
Matrices	6	Applications of Derivatives	9
Trigonometric Functions	10	Indefinite Integration	10
Pair of Straight Lines	6	Definite Integration	6
Vectors	12	Differential Equations	8
Line and Plane	10	Probability Distribution	5
Linear Programming (LPP)	4	Binomial Distribution	5

Focus on Vectors and Trigonometric Functions first. These two chapters alone contribute nearly 20% of your total marks!

Important Questions for Part 1: Algebra & Geometry

Part 1 is generally more scoring because it involves procedural logic and geometric visualization. Here are the most expected HSC Maths Science important questions 2026 for Part 1:

1. Mathematical Logic

• Construct truth tables for complex statements like $(p \land q) \left right arrow (p \lor r) $.

• Examine whether a statement pattern is a Tautology, Contradiction, or Contingency.

• Important Theorem: Duals of statements and Negation of compound statements.

2. Matrices

• Find the inverse of a $3 \times 3$ matrix using the Adjoint Method.

• Solve a system of linear equations using the Method of Inversion or Reduction.

• Calculate the cofactor and minor of specific elements in a matrix.

3. Trigonometric Functions

• Find the General Solution for $\sin \theta = k$, $\cos \theta = k$, and $\tan \theta = k$.

• Must-Know Theorem: The Sine Rule, Cosine Rule, and Projection Rule.

• Problems involving Inverse Trigonometric Functions (e.g., proving $\tan^ {-1}x + \tan^ {-1} y$ identities).

4. Vectors & 3D Geometry

• Find the volume of a parallelopiped and tetrahedron using the Scalar Triple Product.

• Important Theorem: Section formula for internal and external division.

• Find the shortest distance between two skew lines.

Important Questions for Part 2: Calculus & Statistics

Calculus is the "heart" of the Science stream syllabus. While it can be challenging, the questions often follow predictable patterns.

1. Differentiation & its Applications

• Differentiate functions using the Chain Rule, Logarithmic Differentiation, and Parametric Functions.

• Find the equations of Tangents and Normals to a curve.

• Solve "Maxima and Minima" word problems—these are frequent 4-mark questions in Section D.

2. Integration (Indefinite & Definite)

• Integrate using "Substitution" and "By Parts" ($u \c dot v$ rule).

• Important Theorem: Prove $\int_ {0} ^{a} f(x) \, dx = \int_ {0} ^{a} f(a-x) \, dx$ and its applications in Definite Integrals.

• Find the area bounded by a curve and a line (Application of Definite Integration).

3. Differential Equations

• Form a differential equation by eliminating arbitrary constants.

• Solve equations using the Variable Separable Method and Linear Differential Equations.

4. Probability & Binomial Distribution

• Find the Probability Mass Function and Expected Value $E(X)$.

• Solve word problems based on the Binomial Distribution formula.

Top 5 Study Strategies for HSC 2026

1. The "Textbook" Rule: 90% of the Maharashtra Board paper is derived directly from the Bal Bharati textbook. Master every "Miscellaneous Exercise."

2. Theorems are Free Marks: At least 12–15 marks in the paper come from direct theorem proofs. Dedicate a separate notebook to practicing these daily.

3. Step-Marking: In 2026, examiners are instructed to give marks for every correct step, even if the final calculation is wrong. Always write the formula first.

4. Time Management: Solve at least 5 full-length mock papers under a 3-hour timer to avoid leaving Section D incomplete.

5. Use college simplified Resources: For chapter-wise PDFs and the latest marking scheme updates, visit collegesimplified.in.
