Half of your CBSE Class 10 board paper no longer tests what you remember. It tests what you can do with what you know. Since the 2024–25 academic session, competency-based questions have made up 50% of the theory paper across every major subject — Maths, Science, Social Science, and English — and this structure has stayed unchanged through 2025–26 and into the current 2026–27 session. If you're preparing for boards using older notes, older question banks, or a study method built around memorising model answers, you're preparing for a paper that no longer exists in that form.
This guide covers exactly what competency-based questions are, the five distinct forms they take, how they show up differently across subjects, and — most usefully — how to actually practise for them using CBSE's own official resources.
You may come across older articles online citing a lower figure — around 30% — for competency-based questions. That figure reflects an earlier stage of this shift, before CBSE raised the weightage to 50% starting the 2024–25 session. Multiple current sources, including CBSE's own public statements around the 2025 results, confirm 50% as the correct and current figure, unchanged for 2026–27. If a resource you're using still says 30%, it's likely out of date — check the publication date before relying on it.
The Paper Is Now Split Three Ways — Not Just MCQ vs Descriptive
Every 80-mark theory paper in a major Class 10 subject now breaks down into three distinct categories, not the old simple binary of "objective vs subjective":
Case studies, source-based questions, data interpretation, assertion-reason, and application-style MCQs — testing whether you can use a concept, not just state it.
Direct, single-answer objective questions testing factual recall and straightforward concept identification.
Short and long answer questions requiring written explanation, derivation, or structured multi-step answers.
This means a student who has only ever practised "define X" or "state the formula for Y" is only genuinely prepared for a fraction of the paper. The other half requires reading a scenario, extracting what's relevant, and applying the right concept — a skill that has to be practised specifically, separately from content memorisation.
The Five Types of Competency-Based Questions — and How to Approach Each
Competency-based questions aren't one uniform question type. They take five distinct forms, each requiring a slightly different reading and answering approach:
Case-Based Questions
A real-world scenario or short story sets up a situation, followed by several linked questions — typically appearing in the paper's final section, worth 3–4 marks per question.
Example pattern: a passage describes a small business tracking its monthly expenses, followed by questions asking you to calculate values and interpret trends using concepts from the relevant chapter.
✓ Tip: Read the entire scenario once before attempting any sub-question — later questions often depend on details established earlier in the passage.
Source-Based Integrated Questions
A passage, image, map, cartoon, or data table is provided, and you answer multiple questions by analysing it directly — common in Social Science and Science.
Example pattern: a labelled map or historical source excerpt is given, followed by questions asking you to identify features, interpret context, or draw conclusions from what's shown.
✓ Tip: Underline or mentally flag key data points in the source before reading the questions — this prevents re-reading the whole source for every sub-part.
Assertion-Reason Questions
Two linked statements are given — an Assertion and a Reason. You evaluate whether each is individually true, and whether the Reason correctly explains the Assertion. Especially common in Science, particularly Chemistry.
Example pattern: Assertion — a stated fact about a concept. Reason — a stated explanation. You determine both truth and logical connection between the two.
✓ Tip: Evaluate the Assertion and Reason as two separate true/false judgements first, then check the logical link — don't judge the connection before confirming both are individually correct.
Data Interpretation Questions
A graph, chart, or numerical dataset is provided, and questions require you to read, calculate, or infer from it directly — increasingly common in Maths, Science, and even English unseen passages framed around infographics.
Example pattern: a bar graph or table of values is given, followed by questions asking for a specific calculation, trend identification, or comparison drawn from the data.
✓ Tip: Note the units and scale on any graph or table first — misreading these is the single most common error in this question type.
Application-Based MCQs
Multiple choice, but framed around a situation rather than direct recall — you can't answer from memory alone, you have to work through the scenario to eliminate options.
Example pattern: instead of "define X," the question describes a situation and asks which option correctly explains or resolves it, requiring you to apply the concept rather than simply state it.
✓ Tip: Treat these like short case-based questions, not quick-recall MCQs — budget more time for them than for standard objective questions.
How Competency Questions Show Up Differently by Subject
Mathematics
Competency questions typically cluster in the paper's final section as case-based problems worth 4 marks each — built around genuinely real-world scenarios (park dimensions, transport schedules, sports statistics) that require applying concepts from coordinate geometry, statistics, or algebra rather than solving an isolated equation.
Science
Assertion-reason questions are especially prominent, particularly in Chemistry. Data interpretation appears through graph-based questions on topics like reaction rates or motion. Case-based questions often connect concepts to everyday situations — electrical circuits at home, or biological processes in daily life.
Social Science
Source-based questions dominate — map work, historical excerpts, political cartoons, and economic data tables. These reward students who've engaged with the source material in NCERT (including the source boxes many students skip) rather than only reading the main narrative text.
English
Unseen passages are increasingly infographic or data-based rather than purely textual, requiring you to extract information from a visual format under time pressure — a genuinely different skill from reading a traditional prose passage.
How to Actually Prepare — Using CBSE's Own Official Resources
The most effective preparation for competency-based questions starts with genuine conceptual clarity, not additional memorisation. You can't apply a concept you don't actually understand — so the first step is always making sure your NCERT foundation is solid, not skipping ahead to practice questions before the underlying concept is clear.
A resource most students don't know exists
CBSE, in collaboration with Educational Initiatives (Ei), publishes Competency Focused Practice Questions (CFPQ) — free, chapter-wise practice booklets with detailed solutions, available directly on the official CBSE Academic website (cbseacademic.nic.in). These are prepared by CBSE itself, which means they reflect the actual question style far more reliably than most third-party guides.
If you find CFPQ material on a third-party site behind a paywall, that isn't the official source — the genuine CFPQ resources are free.
Once your concepts are solid, work through official CBSE sample papers under timed conditions. This does two things: it shows you the actual current format (rather than an outdated one), and it builds the specific skill of pacing yourself across five different question types in one sitting — which is a genuinely separate skill from knowing the content.
Why "I Know the Concept But Still Got It Wrong" Needs a Different Kind of Tracking
Competency-based questions create a specific diagnostic problem: a student can genuinely understand a concept and still lose marks — not because of a knowledge gap, but because they misread the case, applied the right concept to the wrong part of the scenario, or ran out of time. A simple score doesn't tell you which of these actually happened. And without knowing which one, you can't fix the right thing.

Questions Students Commonly Ask
Quick answers to the most common questions related to this guide.
What percentage of the CBSE Class 10 board paper is competency-based?
50% of the CBSE Class 10 theory paper is competency-based, with the remaining split as 20% standard MCQs and 30% descriptive (short and long answer) questions. This structure was raised to 50% starting the 2024-25 academic session and has remained unchanged through 2025-26 and into 2026-27. Some older articles online still reference a lower figure of around 30%, which reflects an earlier, since-superseded stage of this shift — 50% is the current, confirmed figure.
What are the different types of competency-based questions in CBSE Class 10?
CBSE Class 10 competency-based questions generally take five forms: (1) Case-based questions — a real-world scenario followed by multiple related questions; (2) Source-based integrated questions — a passage, image, map, or data source with questions built around it; (3) Assertion-reason questions — two linked statements you must evaluate for individual truth and logical connection; (4) Data interpretation questions — graphs, tables, or datasets requiring calculation or inference; (5) Competency-style or application-based MCQs — multiple choice questions framed around a situation rather than direct recall.
Which subjects have the most competency-based questions in Class 10?
Science, Mathematics, Social Science, and English have seen the greatest emphasis on competency-based content. In Science, particularly Chemistry, assertion-reason questions are especially common. In Mathematics, competency questions typically appear as case-based problems in the final section of the paper, worth 4 marks each, often built around real-world scenarios like designing a park or calculating a metro schedule. Social Science tends to favour source-based and map-based questions. English increasingly uses infographic or data-based unseen passages rather than purely textual ones.
How should I practise for competency-based questions in CBSE Class 10?
Start by building genuine conceptual clarity from NCERT rather than memorising answers, since competency questions specifically test whether you can apply a concept in an unfamiliar situation. Use CBSE's own official Competency Focused Practice Questions (CFPQ), prepared in collaboration with Educational Initiatives and available free on the CBSE Academic website, as chapter-wise practice with solutions. Practise official CBSE sample papers under timed conditions to get used to the actual format. When answering case-based or source-based questions, read the full passage carefully before attempting any question, underline key data, and avoid rushing straight to an answer.
Why did CBSE increase the weightage of competency-based questions?
The shift is part of CBSE's alignment with the National Education Policy (NEP) 2020, which pushes Indian education away from rote memorisation toward critical thinking, problem-solving, and real-world application. The 2025 National Achievement Survey found that only 37% of Class 8 students could apply mathematical concepts to real-life problems, which added urgency to this reform. CBSE has stated the goal is to test whether a student can think, not merely recall.
