CBSE Class 10 Science Board Exam 2026: Case-Based Questions with Quick Solving Strategies

The CBSE Class 10 Science Board Exam 2026 tests understanding of concepts, not just memorisation. One of the most important parts of the paper is case-based questions. These questions check whether you can apply concepts to real-life situations, experiments, graphs, and data-based scenarios.

Many students lose marks not because they don’t know the concept, but because they:

• Take too much time reading the case

• Panic after seeing a long paragraph

• Miss important keywords

• Make small calculation mistakes

• Forget formulas

If you learn the right approach, case-based questions become one of the highest scoring sections in the paper.

What Are Case-Based Questions in Class 10 Science?

Case-based questions usually include:

• A short paragraph or situation

• Sometimes a diagram, graph, or table

• 3–5 sub-questions based on that case

These questions may come from:

Physics

Electricity, Light, Magnetic Effects, Human Eye, etc.

Chemistry

Acids & Bases, Metals & Non-metals, Carbon Compounds, Chemical Reactions, etc.

Biology

Life Processes, Control & Coordination, Heredity, Environment, etc.

The goal is to test:

• Concept clarity

• Application skills

• Logical thinking

• Interpretation ability

Why Case-Based Questions Are Important in 2026

CBSE now focuses on:

• Competency-based questions

• Real-life applications

• Concept-based understanding

Case-based questions carry good weightage and are usually direct if concepts are clear.

They help you:

• Score quickly

• Save time

• Gain confidence early in the exam

Quick Solving Strategy for Case-Based Questions

Follow this simple 5-step method in the exam:

Step 1: Identify the Chapter in 10 Seconds

Scan for keywords.

If you see:

• Resistance, Current → Electricity

• Focal length, Image → Light

• pH, Neutralisation → Acids & Bases

• Photosynthesis → Life Processes

Your brain should immediately connect to the chapter.

Step 2: Underline Key Information

While reading, underline:

• Numbers

• Units

• Important conditions

• Increase/decrease words

Do NOT underline full sentences. Focus only on useful data.

Step 3: Solve Easy Sub-Questions First

Usually:

• 1–2 questions are direct

• 1 question may need calculation

• 1 question may test understanding

Answer easy ones first. Leave tricky ones for later.

Step 4: Use Elimination Method in MCQs

Instead of finding the correct answer directly:

• Remove 2 clearly wrong options

• Compare the remaining 2

• Check units and signs

This saves time.

Step 5: Watch Units and Sign Conventions

Especially in:

• Optics

• Electricity

• Magnetic Effects

Small sign mistakes can cost marks.
