What are CBSE important questions?
CBSE important questions are a curated shortlist of the questions most likely to appear in your exam. Instead of re-reading a whole chapter blindly, you practise the exact question types — and the exact topics — that CBSE keeps testing. Each question on Classmate AI comes with a model answer written the way an examiner expects, so you learn not just what to answer but how to write it for full marks.
They are organised the way you actually study: class → subject → chapter. So when you sit down to revise a single chapter, you land on a page with just that chapter’s most-important questions — nothing to hunt for.
How we choose the important questions
Every chapter’s list is built from four signals, not guesswork:
- Previous-year papers — questions and patterns CBSE has repeatedly asked.
- Sample papers — the official blueprint for the current NCERT 2026–27 pattern.
- Marks weightage — chapters and topics that carry the most marks get more coverage.
- Question-format balance — a mix of every format, from 1-mark MCQs to 5-mark long answers.
The question types you’ll practise
The CBSE paper is assembled from a set of question formats. Our important questions cover every one, so nothing on exam day is unfamiliar:
| Question type | Marks | What it tests |
|---|---|---|
| Multiple Choice (MCQ) | 1 | One correct option — tests quick recall and concept clarity. |
| Assertion–Reason | 1 | Judge a statement and its reason — a competency-based format. |
| Very Short Answer (VSA) | 2 | One or two steps — definitions, one-line derivations, single sums. |
| Short Answer (SA) | 3 | A short worked solution or a 3–4 point explanation. |
| Long Answer (LA) | 5 | Full multi-step problems, derivations and detailed answers. |
| Case / Source-based | 4 | A passage or data set with 3–4 linked sub-questions. |
| Diagram & Numerical | varies | Labelled diagrams and numericals with units and full working. |
How to use them to score more
- Learn first, then test. Finish the chapter from your textbook before opening the important questions.
- Attempt before you peek. Try each question on paper, then compare with the model answer.
- Fix the misses. Re-attempt anything you got wrong the same day — that’s where marks are won.
- Time a final pass. The day before the exam, do one quick run through all of a chapter’s questions.
- Ask when stuck. If a concept still won’t click, let the Classmate AI tutor walk you through it step by step.
