CBSE Class 10 Syllabus 2027: Overview
CBSE prescribes the Class 10 syllabus for all affiliated schools across India and abroad. The CBSE Class 10 2026–27 syllabus — valid for board exams in 2027 — is based on NCERT’s rationalized curriculum. CBSE streamlined this curriculum in 2022–23 to reduce student burden while retaining core concepts. The syllabus has remained stable since then.
A landmark policy change applies for 2027: CBSE now conducts two board examinations for Class 10. Exam 1 (compulsory) is in February–March 2027. Exam 2 (optional) in May–June 2027 lets students improve their scores. Both sittings cover the complete 2026–27 syllabus.

| Board Exam 2 — Optional Improvement | May–June 2027; same syllabus, same paper design; open to all Class 10 students |
| Syllabus Coverage (Both Exams) | Full 2026–27 syllabus — no split syllabus between the two sittings |
| Theory Marks | 80 marks per subject |
| Internal Assessment | 20 marks (awarded by school throughout the year) |
| Question Type Distribution | Competency-based questions: 40% | Subjective questions: 40% | Objective / MCQ: 20% |
| Duration of Each Paper | 3 hours |
| Medium | English / Hindi (subject-wise choice) |
| Passing Criteria | 33% aggregate in each subject (theory + internal combined) |
CBSE Class 10 Internal Assessment Breakdown (20 Marks)
| Component | Marks | How It Is Assessed |
|---|---|---|
| Periodic Tests | 5 | Best of two written periodic tests conducted by the school |
| Multiple Assessments | 5 | Quizzes, oral tests, concept maps, group tasks during the year |

CBSE Class 10 Preparation Tips 2027
The Two Board Exam system gives you more opportunities in 2026–27. Plan your preparation to be fully ready for Exam 1 in February–March 2027 — treat Exam 2 in May–June 2027 as a bonus opportunity, not a fallback. Use the subject-wise tips below to structure your study from today.
Mathematics
- Algebra contributes 20 out of 80 marks — spend at least 30% of your Maths study time on its four chapters.
- Practice Quadratic Equations daily; both factorisation and discriminant-based questions appear in every paper.
- For Geometry, write out theorem proofs by hand — CBSE board questions often ask for proof in full.
- Complete NCERT exercises for each chapter before moving to RD Sharma for additional practice.
- Competency-based questions make up 40% of the paper — solve at least five full previous-year papers under timed conditions.
Science
- Units I and II carry 50 out of 80 marks — begin with Chemical Substances, then World of Living.
- Draw all key diagrams from memory (human eye, reflex arc, neuron, digestive system, reproductive system, electric circuit).
- For Chemistry, understand reaction mechanisms and reasons — CBSE asks "why" questions, not just definitions.
- Complete all 14 prescribed practicals listed in your school’s lab manual before the practical exam.
- Do not waste time on the three deleted chapters (Periodic Classification, Sources of Energy, Management of Natural Resources).
Social Science
- All four disciplines carry equal 20-mark weightage — give balanced time to History, Geography, Civics, and Economics.
- Map work carries 5 marks — practice locating all specified places on a blank outline map of India.
- For History, focus on causes, consequences, and key personalities — boards ask analytical long-answer questions.
- For Economics, study all data tables in the NCERT chapters carefully; case-study questions are often based on them.
- Revise Civics terminology (federalism, power sharing, political parties) precisely — short answers test exact terms.
English Language and Literature
- Literature (40 marks) is the highest-scoring section — read every prescribed text from First Flight and Footprints Without Feet.
- For Reading (20 marks), practice unseen passages timed at 30 minutes to build speed and accuracy.
- In Writing and Grammar (20 marks), memorise CBSE’s prescribed format for formal letters and articles.
- For grammar, revise tenses, reported speech, and modals using gap-fill exercises from previous-year papers.
- For poetry, learn the central idea, themes, and key poetic devices for each of the eleven prescribed poems.
Hindi (Course A)
- Read only the chapters listed in the official 2026–27 syllabus — several NCERT Kshitij and Kritika chapters are excluded.
- Grammar (Vyavaharik Vyakaran, 16 marks) requires dedicated daily practice — focus on Vachya, Pad Parichay, and Ras.
- For creative writing (Rachnatmak Lekhan, 20 marks), practise formal Hindi letter formats — application and complaint.
- Understand the central idea and characters of each prose chapter — CBSE asks comprehension and character-based questions.
