How to Prepare for CBSE Class 10 Board Exams

Starting Point: Know the Exam

CBSE Class 10 board examinations are typically held in February–March. For 2026-27, boards are likely in February–March 2027.

Subjects: Mathematics Standard/Basic, Science, Social Science, English Language and Literature, Hindi A/B, plus one language or vocational subject.

Marks: Most papers are 80 marks (theory) + 20 marks (internal assessment). The 20-mark internal includes: periodic tests (10), notebook submission (5), subject enrichment (5).

Passing criteria: Minimum 33% in written exam + at least 33% combined (written + internal). Compartment exams are available for students who fail in one or two subjects.

Key insight: Class 10 board exams test NCERT content primarily. 90%+ of questions are directly or indirectly from NCERT textbooks and exemplar. This makes preparation very focused — NCERT mastery is the core strategy.

When to Start Preparing

If you are starting from July–August (academic session beginning): You have 7–8 months. This is the ideal scenario — build strong foundations alongside school, and use October–March for intensive revision and practice tests.

If you are starting in October–November: 4–5 months is plenty for a focused student. Prioritise high-weightage chapters in each subject and spend most of your revision time on past papers and CBSE sample papers.

If you are starting in December–January: 2–3 months is tight but manageable. Focus exclusively on high-weightage chapters, practice only past papers (not additional books), and ensure the internal assessment marks are secured.

In all cases: Do not leave any subject entirely unprepared. Even 1–2 days per low-priority subject is better than zero — you need 33% to pass each individual subject.

Subject-wise Strategy: Mathematics

Marks: 80. Duration: 3 hours. Comprises MCQs, short answer (2-3 mark) and long answer (5 mark) questions.

High-weightage chapters: Real Numbers, Polynomials, Quadratic Equations, Arithmetic Progressions, Triangles, Circles, Trigonometry, Surface Areas and Volumes, Statistics, Coordinate Geometry.

Strategy: Maths requires practice — reading is not enough. Solve every NCERT exercise problem. Then solve CBSE sample papers and previous year papers under timed conditions (3 hours). Focus on showing every step clearly — step marks are awarded even when the final answer is wrong.

Common error areas: Students lose marks by not writing units, not simplifying surds, skipping intermediate steps in geometry proofs. Write every step.

For weaker students: Focus on algebra (Polynomials, Quadratic Equations) and Statistics/Probability — these are more formulaic and learnable in shorter time. Avoid skipping chapters entirely.

Subject-wise Strategy: Science

Marks: 80. Three sections: Physics, Chemistry, Biology.

High-weightage chapters: Chemical Reactions, Acids Bases Salts (Chemistry); Life Processes, Heredity and Evolution (Biology); Electricity, Magnetic Effects (Physics). These chapters are consistent across CBSE board papers.

Strategy: Science requires both understanding and memorisation. For Physics — understand the concepts and solve all numerical problems (Electricity Ohm's law problems, optics mirror/lens formula). For Chemistry — write chemical equations neatly with conditions; balance every equation. For Biology — draw and label every diagram (heart, brain, reproductive system, eye, ear) — a labelled diagram earns full marks independently.

NCERT is essential: All in-text questions and chapter-end exercises are exam-relevant. The NCERT Exemplar has harder problems that sometimes appear in board papers.

Practical skills: The 20-mark practical includes lab experiments and viva. Know the standard experiments (wire resistance, refraction, starch test in leaves, osmosis) for viva preparation.

Subject-wise Strategy: Social Science

Marks: 80. Four sections: History, Geography, Civics, Economics.

High-weightage chapters: Nationalism in India, Print Culture (History); Resources and Development, Water Resources, Agriculture (Geography); Power Sharing, Federalism, Democracy (Civics); Development, Money and Credit (Economics).

Strategy: Social Science is the highest-marks-per-study-hour subject — it rewards focused reading and answer writing more than any other subject. Read NCERT chapters carefully. Make structured notes with bullet points for each chapter.

Map work: Mandatory in Geography — practice 15–20 outline maps before the board exam. Rivers, mountains, states, cities, resources and agricultural zones are mapped. Use CBSE-prescribed blank maps.

Answer writing: 3-mark and 5-mark questions require well-structured answers. Use subheadings. For 5-mark answers, give a brief introduction, 3–4 body points, and a brief conclusion. Source-based questions (from passages) require reading the given source carefully and deriving answers from it.

Subject-wise Strategy: English

Marks: 80. Reading, Writing, Grammar, Literature.

Strategy: English rewards regular reading habits built over months more than last-minute cramming. For reading comprehension — practise unseen passages regularly (10–15 practice passages before the exam). For writing — write 5–6 essays and letters under timed conditions; get them evaluated.

Grammar: Rules are finite — master tenses, voice, reported speech, sentence transformation. Solve 50+ grammar exercises from CBSE sample papers.

Literature: Know the NCERT texts (First Flight, Footprints Without Feet) deeply — character analysis, themes, extract-based questions. Write 5–10 practice long answers on important characters and themes. The long answer questions in Literature (5 marks each) are where high scorers differentiate themselves.

Vocabulary: Learn 10–15 new words per week from your reading. Synonyms, antonyms and one-word substitution appear in papers.

The 3-Month Intensive Revision Plan

Month 1 (3 months before exam): Complete all NCERT chapters for every subject. Do in-text exercises and chapter questions. Focus on building full chapter coverage — do not skip.

Month 2 (2 months before): Solve CBSE sample papers (released by CBSE) for each subject. Time yourself. Identify weak chapters and re-read them. Begin map work practice for Geography. Begin writing practice for English and Social Science.

Month 3 (1 month before): Solve 5–10 previous years' actual board papers (2018–2024) per subject. Do these under real exam conditions — no notes, 3-hour sessions. Mark yourself using the official marking scheme. The gap between your marks and the marking scheme answer is your revision priority.

Final week: Light revision only — notes, formulas, key definitions, NCERT in-text Q&A. No new topics. Sleep 8 hours every night. Keep all stationery and admit card ready.
