Class 12 Maths Chapter-wise Important Questions
The five chapter clusters below carry the bulk of the CBSE 2026 Class 12 Maths paper and repeat almost every year. The first column lists the long-answer topics that recur as 3-mark and 5-mark questions; the second column lists the application-level questions that appear as 1-3 mark numericals / MCQs / case-studies in CBSE and JEE Main.
| Chapter Cluster | Important Derivations / Theorems (3-5 marks) | Important Application Problems (1-3 marks) |
|---|---|---|
| Relations, Functions and Inverse Trig (Ch 1-2) | 1. Composition of functions and one-one onto proof. 2. Properties of inverse trigonometric functions. 3. Derivation of principal-value branches. | Domain and range of inverse trig, simplification of complex inverse-trig expressions. |

The same five clusters appear in JEE Main 2026 with a near-identical split - Calculus alone delivers 8-10 of the 25 JEE Main Maths questions every cycle. The Expert's Solution tab on each chapter page works the JEE-style alternative method alongside the CBSE board-style minimum-steps version.
EXEMPLAR SOLUTIONS · CLASS 12 MATHS
Class 12 Maths - Exam Weightage
Class 12 Maths contributes roughly 240 marks combined across CBSE Boards, JEE Main and JEE Advanced - Maths is not tested in NEET, but it is the single largest engineering-entrance scoring block.
Class 12 Maths Weightage Snapshot (CBSE 2026 Theory Paper)
Exemplar Solutions effort scales with chapter weightage. Calculus delivers 35 marks of the 80-mark paper - also where the bulk of the harder Exemplar problems sit.
| Unit | Chapters | CBSE Marks (2026) | JEE Main 2025 Qs |
|---|---|---|---|
| Calculus | Ch 5, 6, 7, 8, 9 | 35 marks | 8-10 |
| Vectors and 3D Geometry | Ch 10, 11 | 14 marks | 3-4 |
| Algebra | Ch 3, 4 | 10 marks | 2-3 |
| Relations and Functions | Ch 1, 2 | 8 marks | 2 |
| Probability | Ch 13 | 8 marks | 1-2 |
| Linear Programming | Ch 12 | 5 marks | 0-1 |
Class 12 Maths CBSE 2026 Paper Pattern Snapshot
The 80-mark CBSE Class 12 Maths theory paper runs 3 hours and is split into five sections. Knowing the section-by-section weight is half the revision plan; once you know which section a chapter feeds, you can pick the right resource (Notes for Section A recall, NCERT Solutions for Sections C and D working).
- Section A (20 questions of 1 mark each): MCQs and assertion-reason questions; covers definitions, identities, and direct-substitution numericals.
- Section B (5 questions of 2 marks each): Very short answer; one-step problems testing formula recall and standard procedures.
- Section C (6 questions of 3 marks each): Short answer; integration, derivatives, matrix-determinant evaluations, simple probability.
- Section D (4 questions of 5 marks each): Long answer; differential equations, definite integral applications, 3D-geometry combined problems.
- Section E (3 case-study questions of 4 marks each): Application of calculus or probability to a real-world scenario; sub-parts test reading comprehension as much as maths.
The 80-mark theory paper combined with the 20-mark internal assessment (practical, project, viva) makes the 100-mark scheme. Internal assessment marks scale linearly with lab-notebook completeness and viva preparation; the theory paper is where the chapter-wise NCERT preparation actually shows.
Where to Start in the Class 12 Maths NCERT Exemplar Solutions Index
Start with the six high-weightage chapters where worked Exemplar practice delivers the largest competitive-exam mark boost. Together these six chapters cover 62 of 80 board marks:
- Chapter 7, Integrals (part of the 35-mark Calculus block): the largest single chapter in the syllabus. Integration techniques and the fundamental theorem are the highest-yield revision focus.
- Chapter 5, Continuity and Differentiability (Calculus block): the gateway to the rest of Calculus. The chain rule and implicit differentiation problems repeat across JEE Main and CUET.
- Chapter 6, Application of Derivatives (Calculus block): rate of change, maxima-minima, and tangent-normal problems are CBSE 5-mark question staples.
- Chapter 11, Three Dimensional Geometry (8 marks within the 14-mark Vectors+3D block): equation-of-plane and shortest-distance problems are routine LA slots.
- Chapter 9, Differential Equations (Calculus block): formation and solution of first-order linear differential equations are board-paper staples.
- Chapter 13, Probability (8 marks): Bayes' theorem and conditional probability problems repeat year after year.

How to Use the Class 12 Maths NCERT Exemplar Solutions Most Effectively
5-STEP METHOD · CBSE TOPPER ROUTINE
How to Use the Exemplar Solutions - Class 12 Maths
- 1Read the chapter first. Open the NCERT Book PDF or chapter Notes - the resource assumes you understand the concepts already.
- 2Attempt each question on your own. Write the working in a notebook before opening the answer - passive reading does not build exam fluency.
- 3Compare your working to the resource. Mark every step where your approach differed - those are the spots that lose marks on the board paper.
- 4Flag questions taking over 7 minutes. These go on the re-attempt list for the final-week revision pass.
- 5Mark every question that took over 10 minutes. Those are the ones worth a third pass in the final week - Exemplar problems repeat ideas, so the slow ones today become quick ones a fortnight later.
- After each chapter's back-exercise: attempt the Exemplar problems on your own first, then compare your working against the Solutions.
- Within 2 months of JEE / CUET: work every SA and LA Exemplar problem of the high-weightage chapters. Use the Expert's Solution tab for the longer working.
- 1 month before the boards: revisit the marked-difficult Exemplar problems and re-verify against the Solutions.
- Skip in the final week: Exemplar Solutions are too long for night-before revision; switch to the Notes and Formula Sheet at that point.
Common Mistakes Class 12 Maths Students Make with NCERT Exemplar Solutions
- Sign errors in integration by parts: Chapter 7 students forget the alternating sign in the LIATE-based formula. Write the formula out in full before substituting.
- Confusing maxima vs minima at the second-derivative test: Chapter 6 students invert the sign convention. Maximum is where the second derivative is negative; minimum is where it is positive.
- Forgetting the +c on indefinite integrals: CBSE deducts a half-mark per missing constant of integration. Carry it through every step.
- Computing matrix products in the wrong order: Matrix multiplication is not commutative. A times B is generally not B times A; Chapter 3 problems test this routinely.
- Treating Bayes' theorem as a single formula instead of a conditional setup: Chapter 13 students often jump to the formula without writing the prior and likelihood explicitly. Show the sample space first.
- Direction cosines vs direction ratios in 3D Geometry: Chapter 11 problems test the distinction. Direction cosines are the cosines of angles with the axes; direction ratios are any scalar multiple of those. Confusing them costs marks.
Student Pulse: What 16,420 Class 12 Maths Students Told Us
What 16,420 students told us about their Class 12 Maths Exemplar Solutions usage
- 71% of students rated Chapter 7 Integrals as the highest-effort chapter, ahead of Chapter 11 Three Dimensional Geometry at 58% and Chapter 6 Application of Derivatives at 52%.
- Most-skipped chapter: Chapter 12 Linear Programming (skipped by ~24% of students despite carrying 5 marks). Toppers flagged this as a high-ROI chapter to reclaim because the graphical-method problems are mechanical once practised.
- Toppers reported that working the Expert's Solution tab on every Chapter 7 Integrals problem added 5-7 marks to their 80-mark theory paper score, mostly through faster integration technique recall.
- The average Class 12 Maths student spent 58 hours across the 13 chapters to finish the NCERT back-exercise once, with Chapters 5, 6, 7, 11 eating the most time per question.

Topper-tested takeaways for Class 12 Maths Exemplar Solutions
- Attempt every Exemplar problem on your own first; the Solutions are a verification tool, not a teaching tool.
- When the Expert's Solution differs from your method, write both in your notebook side by side; the comparison locks in the alternative approach.
- For JEE / CUET, focus the SA and LA Exemplar Solutions on the high-weightage chapters first; the MCQ and MCQ-II sections come second.
- The Exemplar Solutions cover every problem in the Exemplar Book PDF; cross-link by chapter when you find a Solution unclear and need the textbook's worked example for context.
