CBSE Class 10 Preparation Tips 2027
With CBSE introducing two board exam phases in 2026-27, you now have a structured opportunity to improve your scores. Use Phase 1 as your main examination and Phase 2 as a targeted improvement window if needed.
Mathematics
- Algebra (20 marks) is the highest-weightage unit — dedicate at least 30% of your Maths study time to it.
- Complete all NCERT examples and exercises before attempting reference books.
- For Quadratic Equations and Arithmetic Progressions, practise both formula-based and word-problem types.
- Geometry theorems require neat diagram drawing — practise Euclid-style proofs with labelled diagrams.
- Statistics and Probability (11 marks) are scoring and conceptually straightforward. Do not skip them.
- Solve at least five previous year CBSE papers under timed conditions before Phase 1.
Science
- Chemistry (Unit I) and Biology (Unit II) together carry 50 out of 80 theory marks — prioritise these units in your study plan.
- Draw and label all Biology diagrams from NCERT — human eye, brain, nephron, human heart, flower structure.
- For Chemistry, memorise the reactivity series, pH scale, and key chemical equations with conditions.
- In Physics, Ohm’s law circuit problems and ray diagrams for mirrors and lenses are consistently high-scoring areas.
- Practicals contribute 20 marks to your final score. Attend every practical session and maintain your lab record carefully.
Social Science
- All four disciplines carry equal weightage — do not skip History, Geography, Civics, or Economics.
- Map work in Geography is a predictable, high-scoring section. Practise all NCERT map questions regularly.
- For History, focus on cause-and-effect arguments. CBSE board questions are analytical, not just recall-based.
- In Economics, understand concepts deeply — case-based questions are increasing in this section.
- Revise all NCERT in-text questions (the grey boxes and end-of-chapter exercises). These are regularly set in board exams.
English
- Reading comprehension (Section A, 20 marks) improves with daily reading of editorials and feature articles.
- For Section B, memorise the correct formats for formal letters, applications, and report writing.
- Read every chapter and poem from First Flight and Footprints Without Feet — questions can come from any piece.
- Grammar carries steady marks. Practise editing, gap-filling, and rearranging sentences from CBSE sample papers.
Hindi
- Read all prose and poetry from Kshitij (Course A) or Sparsh (Course B). Understand themes, not just summaries.
- Grammar (vyakaran) is fully predictable — cover sandhi, samas, alankar, and ras for guaranteed marks.
- Practise three to four different letter formats (formal and informal) and essay types for the writing section.
- Solve previous year Hindi papers to identify high-frequency question patterns from each chapter.

CBSE Class 10 Syllabus 2027 FAQs
Ques. Is the CBSE Class 10 syllabus 2026-27 the same as last year?
Ans. The CBSE Class 10 syllabus for 2026-27 is largely consistent with the 2025-26 curriculum. CBSE restored the full rationalized syllabus in 2023-24 after the COVID-era reductions. No major new deletions or additions have been officially announced for the 2026-27 session. The five-unit Science structure and the seven-unit Mathematics structure remain unchanged.
Ques. What is the Two Board Exam policy for CBSE Class 10 in 2027?
Ans. From the 2026-27 session, CBSE will conduct two board exam phases for Class 10. Phase 1 (around February–March 2027) is mandatory for all students. Phase 2 (around May 2027) is optional. It is meant for students who want to improve their Phase 1 scores. The higher of the two scores in each subject is retained in the final marksheet.
Ques. Which subject has the highest weightage in CBSE Class 10 Science?
Ans. Chemical Substances – Nature and Behaviour (Chemistry) and World of Living (Biology) each carry 25 marks in the 80-mark theory paper. They are the two highest-weightage units. Together they account for 62.5% of the Science paper. Physics units (Natural Phenomena and Effects of Current) contribute 25 marks combined, and Natural Resources carries 5 marks.
Ques. Is NCERT enough for CBSE Class 10 board exam preparation?
Ans. Yes. NCERT textbooks are sufficient for scoring well in CBSE Class 10 board exams. CBSE frames almost all questions within NCERT content, examples, in-text questions, and end-of-chapter exercises. You should complete all NCERT chapters thoroughly. Reference books like RD Sharma (Maths) and Lakhmir Singh (Science) are useful for extra practice but are not mandatory.
Ques. Where can I download the CBSE Class 10 syllabus 2026-27 official PDF?
Ans. You can download the official CBSE Class 10 syllabus 2026-27 PDF from cbseacademic.nic.in. Go to the Curriculum section and select Secondary Curriculum (Class X). From there, download the PDF for each subject individually. Direct PDF links for Science and Mathematics are available in the subject-wise download table at the top of this article.
Ques. Which are the most important chapters in CBSE Class 10 Mathematics?
Ans. Algebra (Unit II) is the most important unit — it carries 20 marks and includes Polynomials, Quadratic Equations, Arithmetic Progressions, and Pair of Linear Equations. Geometry (15 marks) and Trigonometry (12 marks) are also high-priority. Statistics and Probability together carry 11 marks and are scoring, so do not skip them.
Ques. Has the CBSE Class 10 Science syllabus been revised for 2026-27?
Ans. No major revision has been announced for the CBSE Class 10 Science syllabus for 2026-27. The five-unit framework — Chemical Substances, World of Living, Natural Phenomena, Effects of Current, and Natural Resources — continues unchanged from the structure introduced in 2023-24.
Ques. How many chapters are in the CBSE Class 10 syllabus 2026-27?
Ans. Mathematics has 14 chapters across 7 units. Science covers topics across 5 units integrating Physics, Chemistry, and Biology chapters. Social Science includes 22 chapters across four disciplines (5 chapters each in History, Civics, and Economics; 7 in Geography). English covers 18 prose and poetry pieces across two NCERT textbooks, plus grammar and writing components.
Ques. What books should I follow for Science in CBSE Class 10?
Ans. The NCERT Science textbook for Class 10 is the primary resource — complete every chapter and in-text question. For extra concept clarity and unit-wise practice, Lakhmir Singh and Manjit Kaur (available in separate Physics, Chemistry, and Biology volumes) is widely recommended. For competency-based question practice, use official CBSE sample papers from cbse.gov.in.
Ques. Is Constructions included in the CBSE Class 10 Maths syllabus 2026-27?
Ans. No. Constructions (compass and ruler geometric constructions) was removed from the CBSE Class 10 Mathematics board exam syllabus in an earlier revision cycle. It is not part of the 2026-27 board exam syllabus. You can skip this chapter for your Phase 1 board exam preparation.
Ques. What is the passing marks criterion for CBSE Class 10 board exam 2027?
Ans. You need a minimum of 33% aggregate marks in each subject to pass the CBSE Class 10 board exam. This means at least 33 out of 100 marks per subject, combining theory and internal assessment. There is no separate pass threshold for the theory paper alone — the 33% applies to the aggregate of both components.
Ques. How should I cover the full CBSE Class 10 syllabus in 6 months?
Ans. Divide your preparation into three phases. Months 1–2: complete all NCERT chapters for every subject on a daily rotation. Months 3–4: solve NCERT exercises, attempt previous year CBSE papers, and revise weak topics. Months 5–6: focus on full-length timed mock tests, formula and diagram revision, and targeted improvement in low-scoring areas before Phase 1 in February 2027. Use Phase 2 in May 2027 only if you need to improve specific subjects.
