What Are Competency Based Questions in CBSE? Competency-Based Questions (CBQs) test whether students can apply concepts to solve real-world problems, not just memorize formulas. Introduced under NEP 2020, CBQs now make up 50% of CBSE Class 10 board exams, shifting focus from rote learning to critical thinking and problem-solving skills.
If your child knows Ohm’s Law perfectly but freezes when asked why a 100W bulb glows brighter than a 60W bulb in a circuit, they’re facing the CBQ challenge. This shift has caught thousands of students off guard in recent board exams—not because they didn’t study, but because they studied the wrong way.
Why CBSE Introduced Competency-Based Questions
The National Achievement Survey 2021 revealed a troubling gap: only 37% of Class 8 students could apply mathematical concepts to everyday situations, despite scoring well on memory-based tests. CBSE responded by mandating that 40 out of 80 marks in Science and Maths papers must test competency, not recall.
This isn’t about making exams harder. The same NCERT chapters are tested—the packaging has changed. Instead of asking “State Newton’s Third Law,” the paper now asks: “A swimmer pushes water backward. Explain why she moves forward using Newton’s laws.”
The Three Types of Competency-Based Questions
1. Multiple Choice Questions (Application-Based)
Unlike traditional MCQs that test definitions, these require multi-step reasoning.
Traditional MCQ: “What is the SI unit of resistance?”
CBQ Format: “A 220V supply connects to a resistor drawing 2A. If voltage doubles to 440V, the new current will be: (a) 1A (b) 2A (c) 4A (d) 8A”
The second question doesn’t mention Ohm’s Law—students must recognize V ∝ I when resistance is constant, then apply it.
2. Case-Based / Source-Based Questions (12 Marks Each Paper)
A 100-120 word passage describes a real scenario, followed by 3-4 sub-questions worth 4 marks total. These appear as:
- Science: Q15 (Biology), Q28 (Chemistry), Q38 (Physics)
- Maths: Section E—Q36, Q37, Q38
The passage provides context and data. The answer requires textbook concepts applied to that context.
3. Assertion-Reasoning Questions (4-6 Marks)
Two statements are given:
- Assertion (A): A factual claim
- Reason (R): A potential explanation
Students must evaluate both independently, then determine if R correctly explains A. The four options are:
- (A) Both true, R explains A
- (B) Both true, R doesn’t explain A
- (C) A true, R false
- (D) A false
The trap: students who assume A and R are connected without verifying both facts lose marks consistently.
Traditional vs Competency-Based: The Difficulty Shift
Science Example: Electricity
| Traditional Question | Competency-Based Question |
|---|---|
| “State Ohm’s Law.” (1 mark) | “A household has a 60W bulb and 100W bulb in parallel at 220V. Which has higher resistance? Calculate and explain.” (3 marks) |
| Tests: Memory | Tests: Recognition (P = V²/R), calculation, reasoning |
| Answer: “V = IR” | Answer: “60W bulb has higher resistance. Using P = V²/R: R₆₀ = 807Ω, R₁₀₀ = 484Ω. Lower wattage means higher resistance when voltage is constant.” |
Maths Example: Arithmetic Progressions
| Traditional Question | Competency-Based Question |
|---|---|
| “Find the 10th term of 2, 5, 8, 11…” (2 marks) | “A company produces 50 cars in January. Each month, production increases by 10 cars. What is total production in the first 6 months?” (3 marks) |
| Tests: Formula application | Tests: Scenario recognition (is this an AP?), data extraction, formula selection |
| Answer: a + 9d = 2 + 27 = 29 | Answer: “This is an AP with a=50, d=10. S₆ = 6/2 × [2(50) + 5(10)] = 3 × 150 = 450 cars.” |
Case-Based Question Examples for Practice
Example 1: Maths (Coordinate Geometry)
PASSAGE:
Rahul is planning a community garden. He marks four corners on a coordinate plane: A(0,0), B(6,0), C(6,4), and D(0,4). He wants to install a water fountain at the intersection point of the diagonals AC and BD.
Questions:
- Find the coordinates of the fountain’s location. (1 mark)
- What is the distance between corners A and C? (1 mark)
- The garden’s perimeter needs fencing at ₹50 per meter. Calculate the total fencing cost. (2 marks)
Why This Is a CBQ: Students must recognize this tests midpoint formula, distance formula, and perimeter—without being told which concepts to use.
Example 2: Science (Chemical Reactions)
PASSAGE:
Maya adds 5g of zinc granules to dilute hydrochloric acid in a test tube. She observes bubbles forming and the test tube becoming warm. After 10 minutes, the bubbling stops and a colorless solution remains.
Questions:
- Name the gas produced during the reaction. How would you test it? (1 mark)
- Write the balanced chemical equation for this reaction. (1 mark)
- Why did the test tube become warm? What type of reaction is this? (2 marks)
Why This Is a CBQ: The passage describes observations. Students must identify the reaction (Zn + HCl), recognize H₂ gas production, understand exothermic reactions—connecting multiple concepts.
Why 1-on-1 Tutoring Matters for CBQ Preparation
Mass coaching classes teach formulas and solve 50 sample questions. But CBQs don’t repeat—they test whether you understand why formulas work, not just what they are.
At Angle Belearn, our tutors use diagnostic assessments to identify whether your child is memorizing or understanding. For example, if a student solves “Find the 15th term of 3, 7, 11…” correctly but struggles with the car production scenario above, the tutor knows the issue isn’t mathematical—it’s recognition.
Our personalized approach focuses on:
- Concept mapping: Showing how formulas connect (Ohm’s Law → Power → Energy → Cost)
- Scenario training: Daily practice identifying concepts in unfamiliar contexts
- Question dissection: Teaching students to extract “Given” and “To Find” from paragraphs, not labeled boxes

What are Competency-Based Questions (CBQs) in CBSE?
CBQs test your ability to apply NCERT concepts to real-life scenarios. They are designed to assess logical thinking, reasoning, and problem-solving skills, not just memorization.
How do Competency-Based Questions differ from traditional CBSE questions?
Unlike traditional questions that focus on recall, CBQs require you to recognize and apply concepts in new contexts, such as real-life scenarios and case studies.
How much weight do CBQs carry in the CBSE exam?
CBQs make up 50% of the CBSE Class 10 Science and Maths papers (40 marks out of 80). This change makes them a significant portion of your total exam score.
How can I prepare for Competency-Based Questions?
To prepare, focus on understanding concepts, practice case studies, and learn to apply knowledge to real-life scenarios. Use mock exams and concept maps for efficient practice.
Why are Competency-Based Questions important for CBSE exams?
CBQs test critical thinking and problem-solving skills, ensuring students are prepared for practical application rather than rote memorization. They align with the NEP 2020 initiative to promote application-based learning.
