New CBSE Exam Pattern 2027-28: Competency-Based Questions Explained

The Three Levels of CBQs

How the Dual Exam System Works

Exam 1 (November–December): Covers the full syllabus. This is not a “half-syllabus” exam. You must prepare the entire course. The paper will follow the same 50% CBQ pattern described above. Schools are expected to complete their syllabus by October to give students revision time.

Exam 2 (February–March):

Also covers the full syllabus with fresh question papers. Students who performed well in Exam 1 can choose to skip Exam 2 for specific subjects (subject to CBSE notification). Students who were absent or scored poorly in Exam 1 can appear in Exam 2 without penalty.

Final Score Calculation:

For each subject, CBSE will take the higher of your two scores. If you scored 72 in Mathematics in Exam 1 and 85 in Exam 2, your final score is 85. This system is designed to reduce exam anxiety and give students a genuine second chance — not a “compartment” or “improvement” exam, but a proper second attempt built into the system.

How On-Screen Marking Works

1. You write your exam on the same physical answer sheet as before. Nothing changes in the exam hall.
2. After collection, answer sheets are scanned at high resolution into digital images.
3. Each answer is cropped and assigned to an evaluator digitally. The evaluator sees only one answer at a time on their screen — not the entire sheet.
4. The evaluator marks the answer on screen, and the system automatically tallies the total. There is no manual addition of marks.
5. A random sample of evaluated papers is re-checked by a second evaluator for quality control. If the marks differ significantly, a third evaluator reviews the answer.

What This Means for Your Answer-Writing Strategy

• Write legibly. The evaluator is reading your answer on a screen. Poor handwriting becomes even harder to read when scanned. Use a dark blue or black pen. Avoid gel pens that smudge.
• Do not write in the margins. When the scanner crops your answer, anything written outside the designated area may be cut off. Stick to the printed answer space.
• Start each answer on the correct page. Since answers are cropped individually, if you write part of Question 5's answer in Question 4's space, the evaluator marking Question 5 may never see it.
• Underline key terms and headings. On screen, a wall of text is harder to parse. Use headings, underline important points, and leave space between sub-parts. This helps the evaluator quickly identify the content and award marks.
• Label diagrams clearly. Diagrams must be drawn in pencil (for neatness) and labelled in pen. Ensure labels are large enough to be legible when scanned.
• Number your answers correctly. Mis-numbered answers create confusion in the digital system. Always write the question number clearly at the top of each answer.

Mathematics (Class 10) — Case-Based CBQ

“A municipal corporation is planning a rectangular park in a residential colony. The park must have an area of 1200 sq. metres. Due to existing roads, the length of the park must be 10 metres more than twice its breadth. The corporation also wants to install a walking track along the diagonal of the park.”

Sub-questions: (a) Form a quadratic equation for the breadth of the park. (b) Solve the equation to find the dimensions. (c) Calculate the length of the diagonal walking track. (d) If the walking track costs Rs 250 per metre to install, find the total cost.

Why this is a CBQ: The underlying concepts are quadratic equations and Pythagoras' theorem — both in the NCERT syllabus. But the question wraps them in a real-world scenario (park planning) and requires you to move through four connected steps. You cannot answer part (c) without first solving parts (a) and (b). This tests sequential reasoning, not just formula recall.

Science (Class 10) — Data Interpretation CBQ

“A student measures the current through a resistor at different voltages and records the following data: (2V, 0.4A), (4V, 0.8A), (6V, 1.2A), (8V, 1.5A), (10V, 1.6A).”

Sub-questions: (a) Plot a V-I graph for this data. (b) Does the resistor obey Ohm's Law throughout? Justify. (c) At what voltage does the resistor start deviating from Ohm's Law? Suggest a reason. (d) Calculate the resistance at V = 4V and V = 10V. What do you observe?

Why this is a CBQ: A textbook question would give ideal data that perfectly follows Ohm's Law. This question deliberately includes non-linear data points (at 8V and 10V) to test whether you can identify when a law breaks down. You need to understand the conditions under which Ohm's Law holds, not just its formula.

English (Class 12) — Unseen Passage CBQ

“A passage from a technology magazine discusses how AI-generated art is disrupting the traditional art market. It includes opinions from artists, gallery owners, and AI researchers.”

Sub-questions: (a) Identify the author's stance on AI art. Is it neutral, supportive, or critical? Cite evidence from the passage. (b) How does the gallery owner's perspective differ from the artist's? (c) The passage uses the metaphor “a brush in the hands of an algorithm.” What does this suggest about the relationship between technology and creativity? (d) Write a short response (60–80 words) arguing for or against AI-generated art being displayed in traditional galleries.

Why this is a CBQ: This goes beyond comprehension. Part (c) tests your ability to analyse figurative language in context. Part (d) requires you to form and defend an opinion — a higher-order skill that no amount of memorisation can substitute.

Accountancy (Class 12) — Scenario-Based CBQ

“Ram and Shyam are partners sharing profits in the ratio 3:2. Their Balance Sheet as on 31st March 2028 shows total assets of Rs 12,00,000 and total liabilities of Rs 4,00,000. They admit Mohan as a new partner for 1/4th share. Mohan brings Rs 3,00,000 as capital and Rs 1,50,000 as premium for goodwill. On the date of admission, the following adjustments are required: land is revalued upward by Rs 80,000, stock is written down by Rs 20,000, and an unrecorded liability of Rs 15,000 is discovered.”

Sub-questions: (a) Calculate the new profit-sharing ratio. (b) Prepare the Revaluation Account. (c) Show the distribution of goodwill premium. (d) If Mohan later claims the revaluation gains were unfairly distributed, evaluate whether his claim has merit.

Why this is a CBQ: Parts (a) through (c) are standard partnership accounting. Part (d) is the competency-based twist — it asks you to evaluate a claim about fairness, which requires understanding the logic behind revaluation adjustments, not just the mechanical journal entries.

Step 1: Master the NCERT First (Non-Negotiable)

CBQs are built on NCERT concepts. You cannot apply a concept you do not understand. Read every chapter thoroughly. Understand the why behind every formula, law, and principle. If NCERT says “Ohm's Law states that V = IR,” ask yourself: why does current increase with voltage? What happens at the atomic level? When does this law not hold? These “why” and “when” questions are exactly what CBQs test.

Step 2: Practice CBSE Sample Papers and Previous Year CBQs

CBSE releases official sample papers and marking schemes every year at cbse.gov.in. These are your single best resource. Solve every sample paper under timed conditions. After solving, compare your answers with the marking scheme — not just for correctness but for how the marks are distributed across sub-parts. Notice that CBQ marking schemes often award marks for “identification of relevant concept” and “application to given context” separately.

Step 3: Read Newspapers and Science Magazines

CBQs draw scenarios from real life. A student who reads newspaper articles about climate change, economic policies, technological developments, and public health will find CBQ scenarios familiar rather than intimidating. Spend 15–20 minutes daily reading editorials from any major newspaper. For Science students, magazines like Science Reporter (published by CSIR) are excellent. For Commerce students, the business pages and budget analyses provide ready-made case study material.

Step 4: Create Your Own CBQs

This is the most powerful preparation technique. After studying a chapter, write your own competency-based question. Take a concept and place it in a real-world scenario. For example, after studying chemical reactions, write a question about a bakery (baking soda reacting with acid to make bread rise). The act of creating a CBQ deepens your understanding far more than just solving one.

Step 5: Practice Data Interpretation Daily

Many CBQs present data in tables, graphs, or charts. If you are not comfortable reading graphs quickly and accurately, you will lose time and marks. Practice reading bar graphs, line graphs, pie charts, and data tables from any source — textbooks, newspapers, government reports. Focus on identifying trends, anomalies, and relationships between variables.

Step 6: Solve Inter-Disciplinary Questions

Some CBQs deliberately cross subject boundaries. A Science question might require mathematical calculations. A Social Science question might reference scientific concepts. Do not study subjects in complete isolation. When you learn about industrial pollution in Geography, connect it to the chemical reactions you studied in Chemistry and the ecosystem concepts from Biology. These connections are exactly what higher-level CBQs test.

Step 7: Timed Practice Under Exam Conditions

CBQs take longer to read and process than traditional questions. A case-based question with a 150-word passage followed by four sub-questions can take 12–15 minutes to complete. Practice full papers under strict time limits. Allocate approximately 1 minute per mark: an 80-mark paper should be completed in 80 minutes of a 3-hour exam, leaving time for revision. If you consistently run out of time, your reading speed — not your subject knowledge — is the bottleneck.

Will the NCERT textbook be enough for CBQs?

NCERT is the foundation — every CBQ is built on NCERT concepts. However, you also need to practise applying those concepts in unfamiliar contexts. Use CBSE sample papers, exemplar problems, and real-world case studies to supplement NCERT. The concepts come from NCERT; the application practice must come from additional sources.

Does the 50% CBQ rule apply to all subjects including languages?

Yes. CBSE has confirmed that the 50% competency-based mandate applies across all subjects. For language papers, CBQs take the form of unseen passages with analytical questions, opinion-based writing tasks, and context-dependent grammar questions rather than rote grammar exercises.

If I score well in Exam 1, do I need to appear for Exam 2?

You are not required to appear for Exam 2 if you are satisfied with your Exam 1 score. However, if you want to improve in specific subjects, you can selectively appear for those subjects in Exam 2. The higher score will be taken. Check CBSE notifications for subject-wise flexibility details.

Will on-screen marking change how diagrams are evaluated?

Diagrams will still be evaluated as before, but legibility becomes more important since evaluators view them on screen. Use sharp pencils for drawing, label in ink, and ensure your diagrams are large enough (at least half the available space). Small, cramped diagrams that are readable on paper may become unclear when scanned.

Are CBQs harder than traditional questions?

CBQs are not inherently harder — they test different skills. A student who understands concepts deeply but has poor memorisation skills may actually find CBQs easier than traditional recall-based questions. The difficulty lies in the transition: students trained exclusively on “define, explain, derive” questions need to retrain their approach. With three to four months of targeted CBQ practice, most students adapt comfortably.

How do I prepare for CBQs in Mathematics specifically?

Focus on word problems and real-life applications. After solving a formula-based problem, ask: “Where would I see this in real life?” Practise translating English statements into mathematical equations. Solve CBSE exemplar problems (available free on the CBSE website) — these are designed specifically to build competency-based thinking. For Class 10, focus on chapters like Quadratic Equations, Statistics, and Probability, which lend themselves naturally to case-based scenarios.

Will coaching centres adapt to the new pattern?

Major coaching chains have already started incorporating CBQ-style questions in their test series. However, many smaller coaching centres still rely on rote-based teaching. When evaluating a coaching centre, ask specifically about their CBQ preparation methodology. If they cannot show you sample CBQ worksheets or mock papers, they have not adapted yet.
