What are Competency Based Questions?

CBSE introduced CBQs to test application and analysis skills — not just rote recall.

📖 Case Study Based

Passage + 4–5 Questions

A short passage (real-life or conceptual) is given. 3–4 MCQs and 1 short-answer question follow. Total marks: 4–5. Tests comprehension and application.

Marks: 4–5 per set

⚡ Assertion–Reason

Two Statements, Choose A/B/C/D

An Assertion (A) and a Reason (R) are given. Choose whether both are true, and whether R correctly explains A. Tests logical reasoning and conceptual clarity.

Marks: 1 per question

🗂 Source Based Integrated

Text / Data / Extract + Questions

Common in Humanities — a historical source, literary extract, map, or data table is provided. Questions test inference, analysis, and interpretation skills.

Marks: 4–5 per set

How to Attempt CBQs — 3 Key Tips

01

Read the passage twice

Read the entire passage carefully before attempting any question. The second reading helps you locate specific details quickly when answering.

02

For A-R: a two-step check

First check if both Assertion and Reason are individually true or false. Only if both are true do you then check whether R correctly explains A.

03

All answers are in the passage

For case-study and source-based questions, every answer can be derived from the given passage. Do not bring in outside knowledge — read carefully.
