CBSE Class 10 Case-Study Questions: Chapter-Wise Guide

Open any recent CBSE Class 10 sample paper and the last section looks different from the rest. Instead of a stand-alone question, you get a short passage, a data table or a diagram, followed by three small questions that all depend on it. These are case-study questions, and most students meet them for the first time in the weeks before the board exam, which is exactly when there is no time to learn a new format.

This guide breaks down how cbse case study questions class 10 are built, which chapters in Science, Maths and Social Science tend to produce them, and how to practise so that the section becomes the most predictable four-mark block in your paper. Everything below follows the pattern used in recent CBSE sample papers.

What a Case-Study Question Actually Is

A case-study question gives you a real or realistic situation and then tests whether you can apply a concept to it. The passage is usually three to six lines long. After it come three or four sub-questions, and they are commonly split into smaller mark values that add up to four marks for the whole case.

The format belongs to CBSE’s push towards competency-based questions, which test application and analysis rather than recall. CBSE wants roughly half of the marks in Class 10 to come from competency-based questions. What matters for you is simpler: the answer is almost always hiding in the passage or in one idea from the chapter, and the question is checking whether you can connect the two.

How the Section Is Usually Laid Out

In the sample papers released for the recent board cycles, Section E in Science, Maths and Social Science carries three case-based questions of four marks each, which makes twelve marks. Each case is typically broken into sub-questions worth one, one and two marks.

Two things to keep in mind:

Maths follows the same pattern as Science and Social Science: three cases of four marks each.
Social Science adds a separate map-based question of five marks, which sits outside the case-study block.

The practical meaning is that a student who can reliably pick up the full twelve marks in each of three subjects has a large share of the paper decided before the long answers even start. That is why it is worth practising, and it is also why it connects to the gap described in what separates a 90 from a 95 in CBSE boards.

Science: Which Chapters Give the Best Case Studies

Science case studies work well wherever a chapter has a process, a circuit or a data set that can be described in a paragraph. Use the list below as a practice guide to the chapters that lend themselves to case studies.

Electricity: A household circuit, a table of voltage and current readings, or an electricity bill. Questions ask for resistance, power or energy use. Practise with important questions on Electricity.
Light – Reflection and Refraction: A situation with a mirror or lens, such as a rear-view mirror or a magnifying glass, asking about image nature and position. See the important questions on Light.
Human Eye and the Colourful World: A student who cannot see the board clearly. The questions test defects, correction lenses and scattering.
Life Processes: A diagram or description of the nephron, the heart or photosynthesis in a leaf.
Heredity and Evolution: A cross between two plants or a family tree, asking about dominant traits and ratios.
Carbon and its Compounds: Soap and detergents, ethanol or the properties of a homologous series.
Our Environment and Management of Natural Resources: A food chain, a report on water harvesting, or a pollution scenario.

Chemical Reactions, Acids Bases and Salts, and Metals also show up, usually as a short everyday story, like a rusting gate or an antacid tablet. If you want a free revision resource for each chapter, the MCQ set for Class 10 Science is a quick way to check you remember the base facts that the case will build on.

Maths: Chapters That Usually Carry the Cases

Maths cases tend to wrap a real-life situation around a formula, so the skill is translating words into the right equation. The chapters that fit this style best are:

Applications of Trigonometry: A kite, a tower, a ladder against a wall. Heights and distances are a classic case. Practise with the Application of Trigonometry MCQs.
Arithmetic Progressions: A savings plan, a pattern of seating in a hall, or a stack of pipes.
Quadratic Equations: A rectangular garden, a train journey or a speed-and-time story.
Probability and Statistics: A table of marks, a survey or a bag of coloured balls. See the Probability MCQs and the Statistics MCQs.
Surface Areas and Volumes and Areas Related to Circles: A water tank, a toy made from combined solids, or a circular park with a path.
Coordinate Geometry and Circles: A map on a grid, or a tangent drawn from an external point.

A good habit is to use the chapter-wise important questions for Maths, because many include case-based items with the same sub-part pattern.

Social Science: Source-Based Cases

In Social Science, a case study is a source: an extract from a text, a cartoon, a statistics table or a news snippet. The sub-questions ask you to read the source, link it to what you studied, and sometimes give an opinion backed by one point.

History: Extracts on nationalism, print culture or the making of a global world. Questions ask what the writer is arguing or why an event mattered.
Geography: Tables on land use, cropping patterns, resources or industries.
Political Science: Short stories on power sharing, federalism or political parties.
Economics: Data on money and credit, employment sectors or consumer rights.

Social Science case studies reward answers that quote or refer to the source in the first line. A response such as “As the passage says…” shows the examiner you used the material provided.

A Simple Method for Every Case

Whatever the subject, the same routine works.

Read the sub-questions first. This tells you what to look for in the passage, and you avoid reading the whole thing twice.
Underline numbers and keywords. Units, names, dates and conditions often decide the answer.
Match each sub-question to one concept. If you cannot name the concept in a few words, you are not ready to answer.
Answer in the length the marks suggest. One mark is one line. Two marks are two or three lines with a reason or a formula.
Show the working in Maths and Science. A correct final value with no steps can lose marks in a two-mark part.

Time is part of the plan too. Aim for about five to six minutes per case, and time yourself once on a full set to adjust.

Common Mistakes in Case-Study Answers

Copying the passage. The examiner already knows what is written. Marks go to the inference.
Ignoring units or the data table. A wrong unit can cost a mark even if the number is correct.
Writing a chapter summary. Case questions want one precise answer, not everything you remember.
Leaving the section for last and running out of time. Because the questions are short, they are the easiest marks to pick up early.
Practising only from guides. Use the real CBSE sample papers for Class 10 and the previous-year papers, because the style of language in the passage matters.

If you are already losing marks on long answers, pair this with our guide to writing a 5-mark answer in CBSE Science, since the habits of clear structure carry over to the shorter case parts as well.

A Four-Week Practice Plan

You do not need a new timetable, just a fixed slot.

Week 1: Solve two cases per subject, untimed, and write down the concept each sub-question tested.
Week 2: Solve three cases per subject under the five-to-six-minute target.
Week 3: Attempt the Section E of two full sample papers, then compare your answers with the marking scheme.
Week 4: Redo only the cases where you lost marks, and revise the chapters behind them.

Frequently Asked Questions

Q1. How Many Marks Do Case-Study Questions Carry in CBSE Class 10?

In the recent sample-paper pattern, the case-based section has three questions of four marks each, so twelve marks in Science, Maths and Social Science.

Q2. Are Case-Study Questions Compulsory in the Board Exam?

Yes. Section E is part of the paper in Science, Maths and Social Science. Read the instructions at the start of the section, because some sub-parts carry an internal choice.

Q3. How Do I Score Full Marks in a Case-Study Question?

Read the sub-questions before the passage, underline the data, name the concept for each part and answer to the marks. Show steps in Maths and Science.

Q4. Which Chapters Should I Prioritise for Case Studies?

Start with chapters that describe a situation or data, such as Electricity, Light, Applications of Trigonometry, Probability and the Geography and Economics data tables.

Q5. Where Can I Find Practice Case-Study Questions?

Use the CBSE sample papers and previous-year papers, along with chapter-wise important questions and MCQs for each subject.

Conclusion

Case-study questions look new, but they are a small set of habits: read the sub-questions, find the concept, answer to the marks, and show your working. The chapters most likely to produce cases are the ones where a situation can be described in a few lines, such as Electricity, Light, Trigonometry, Probability and the data-driven parts of Geography and Economics. Use the practice plan above to turn twelve marks per subject into a routine part of your score.
