With the CBSE Class 12 Compartment Exam 2026 scheduled for July 15, 2026, you have 15 days to complete a focused revision and clear your subject with a minimum 33% passing score.
The compartment exam covers the same syllabus as the main board exam, but you only need to clear the subject(s) in which you failed or were absent. A smart 15-day plan built around high-weightage chapters and regular practice tests is the fastest path to passing. This guide gives you the subject-wise chapter priority order, a three-phase daily schedule, and last-minute tips for Mathematics, Physics, Chemistry, Biology, English Core, and Commerce subjects.
- CBSE Class 12 Compartment Exam 2026 starts July 15, 2026 — 15 days remain from July 1.
- You need 33% in theory and 33% overall (theory + practical/internal) to pass each subject.
- Focus on chapters worth 10+ marks first — not full syllabus revision.
- Solve at least 5 full-length previous year compartment papers in the final week.
- NCERT textbooks are your primary source — CBSE sets 80–90% of questions directly from NCERT.

CBSE Class 12 Compartment Exam 2026: 15-Day Revision Schedule
Split your preparation into three clear phases — coverage, practice, and mock tests. Study 6–8 hours daily and give each subject a fixed time slot.
| Phase | Days | Focus |
|---|---|---|
| Phase 1 — Chapter Coverage | Days 1–6 | High-weightage chapters (10+ marks each) from NCERT textbook only |
| Phase 2 — Practice | Days 7–11 | NCERT exercises, solved examples, previous year questions chapter-wise |
| Phase 3 — Mock Tests | Days 12–15 | 3 full-length timed papers, error review, weak chapter re-revision |
Do not start any new chapter after Day 12. The final three days are for consolidating what you already know and building exam-writing speed.
Mathematics: Subject-Wise Chapter Priority
Mathematics carries 80 marks in theory. Calculus alone accounts for approximately 44 marks — it must be your first and longest stop in Phase 1.
| Chapter / Unit | Approx. Marks | Priority |
|---|---|---|
| Integrals and Applications of Integrals | ~20 | P1 |
| Continuity, Differentiability and Derivatives | ~16 | P1 |
| Differential Equations | ~8 | P1 |
| Matrices and Determinants | ~13 | P2 |
| Vectors and 3D Geometry | ~14 | P2 |
| Probability | ~8 | P2 |
| Relations, Functions and Inverse Trigonometry | ~8 | P3 |
| Linear Programming | ~5 | P3 |
Maths revision tip: Solve every NCERT Example and Exercise question in Calculus before moving to any guide. For Matrices, focus on finding the inverse using row operations and solving a system of equations. Attempt 2 full Maths compartment papers in Phase 3 under timed conditions.
Physics and Chemistry: Chapter Priority
Both Physics and Chemistry carry 70 marks in theory. Below is the chapter-wise priority for each subject.
Physics — priority chapter order:
| Chapter | Approx. Marks | Priority |
|---|---|---|
| Ray Optics and Wave Optics | ~14 | P1 |
| Electrostatics | ~8 | P1 |
| Current Electricity | ~7 | P1 |
| Magnetic Effects of Current and Magnetism | ~8 | P1 |
| Electromagnetic Induction and Alternating Current | ~8 | P2 |
| Semiconductor Electronics | ~7 | P2 |
| Dual Nature of Radiation, Atoms and Nuclei | ~7 | P3 |
| Communication Systems | ~5 | P3 |
Chemistry — priority chapter order:
| Chapter | Approx. Marks | Priority |
|---|---|---|
| Aldehydes, Ketones and Carboxylic Acids | ~8 | P1 |
| Amines | ~6 | P1 |
| Haloalkanes and Haloarenes | ~6 | P1 |
| Electrochemistry | ~5 | P1 |
| Coordination Compounds | ~7 | P2 |
| Chemical Kinetics | ~5 | P2 |
| Solutions and Surface Chemistry | ~7 | P2 |
| d and f Block Elements, Polymers, Biomolecules | ~9 | P3 |
Science revision tips: For Physics, write out all key derivations and practice numericals — both carry guaranteed marks. For Chemistry, list all named reactions in Organic Chemistry on one revision sheet and read it every morning in Phase 2.
Biology: Subject-Wise Chapter Priority
Biology theory carries 70 marks. Genetics and Reproduction together account for around 32 marks — cover these two units before anything else in Phase 1.
| Chapter / Unit | Approx. Marks | Priority |
|---|---|---|
| Principles of Inheritance and Variation | ~11 | P1 |
| Molecular Basis of Inheritance | ~7 | P1 |
| Sexual Reproduction in Flowering Plants | ~7 | P1 |
| Human Reproduction and Reproductive Health | ~7 | P1 |
| Organisms and Populations, Ecosystem and Biodiversity | ~14 | P2 |
| Human Health and Disease | ~7 | P2 |
| Microbes in Human Welfare and Biotechnology | ~10 | P3 |
Biology revision tip: Draw and label every diagram from NCERT — examiners deduct marks for unlabelled parts. Revisit all bold-text definitions in NCERT chapters; CBSE sets many 1-mark and 2-mark questions directly from these definitions.
English Core: What to Prioritise in 15 Days
English Core theory is 80 marks, split across Reading, Writing and Literature. Reading and Writing together carry 40 marks and can be mastered in 5 days of focused practice.
| Section | Marks | Priority Action |
|---|---|---|
| Reading Comprehension (2 unseen passages) | ~20 | P1 — practice 2 passages daily; all answers are in the text |
| Writing Skills (Notice, Letter, Article, Report) | ~20 | P1 — memorise the format of each type; practise 2 formats per day |
| Grammar (Gap fill, editing, reported speech) | ~10 | P2 — revise tenses, articles and prepositions |
| Literature — Prose and Poetry (Flamingo and Vistas) | ~30 | P2 — cover all NCERT chapters; prepare theme and character notes per lesson |
English revision tip: For Literature, make a 2-page summary of each lesson with the central theme, key character names, and 2 important quotes. These notes are faster to revise in Phase 3 than re-reading full chapters.
Commerce Subjects: Accountancy, Business Studies and Economics
If your compartment subject is from the Commerce stream, follow this priority order for each subject.
Accountancy (80 marks theory) — chapter priority:
| Chapter / Unit | Approx. Marks | Priority |
|---|---|---|
| Partnership — Admission and Retirement of a Partner | ~20 | P1 |
| Dissolution of Partnership Firm | ~8 | P1 |
| Financial Statements of Companies | ~15 | P2 |
| Cash Flow Statement | ~12 | P2 |
| Issue and Redemption of Debentures | ~10 | P2 |
| Analysis of Financial Statements and Ratios | ~8 | P3 |
Business Studies priority: Cover Planning, Organising, Directing and Controlling first — these units carry the highest theory marks. For Part 2, study Financial Markets and Marketing Management before other chapters, as each carries 12+ marks.
Economics priority: In Macroeconomics, focus on National Income Accounting, Money and Banking, and Balance of Payments. In Microeconomics, cover Consumer Behaviour (Utility and Indifference Curve) and Producer Behaviour (Production and Cost) before other chapters.
Last-Minute Revision Tips for CBSE Class 12 Compartment Exam 2026
- NCERT first and always. Complete all NCERT exercises and solved examples in your subject before opening any guide or notes book.
- Solve 5 previous year compartment papers. Past papers reveal the exact question pattern, mark distribution, and the types of long-answer questions favoured by CBSE.
- Write answers during practice sessions — this builds speed and reduces blanks in the actual 3-hour paper.
- Stop starting new chapters after Day 12. Revising known chapters scores more marks than half-reading new ones.
- Check your CBSE compartment admit card for your exam centre address, reporting time, and subject timing before Day 14 to avoid last-minute stress.
- Sleep 7–8 hours every night. Memory consolidation happens during sleep — cutting rest hours reduces retention of what you studied that day.
