Subject-Wise Preparation Strategy
English — Paper 1 (Language) + Paper 2 (Literature)
English is compulsory and counts towards your percentage. Many students underperform in English Language (Paper 1).
- Paper 1 (Language): Composition (essay/letter/notice), comprehension, grammar (tenses, prepositions, voice, speech), and short stories.
- Paper 2 (Literature): Shakespeare (Merchant of Venice typically), poems, and prose from the textbook.
- Strategy: Practise 2 compositions per week. Solve 10 grammar exercises daily. For Literature, prepare character sketches and theme analysis — do not just memorise summaries.
- Scoring tip: Paper 2 is easier to score in — most questions have definite answers from the text. Paper 1 requires practice.
Mathematics
ICSE Maths is more application-based than CBSE. The syllabus includes topics like GST, banking, and shares that CBSE does not cover.
| Chapter | Weightage | Strategy |
|---|---|---|
| Commercial Mathematics (GST, Banking, Shares) | ~10–15 marks | Formulaic. Practise 20 problems of each type. Easy scoring. |
| Algebra (Quadratic, Ratio, Linear Inequations) | ~20–25 marks | Solve ML Aggarwal fully. Focus on word problems. |
| Coordinate Geometry | ~10 marks | Distance, section formula, slope, equation of line. Formulaic — memorise and practise. |
| Geometry (Circles, Constructions, Similarity) | ~15–20 marks | Theorems with proofs. Constructions need neat diagrams with correct steps. |
| Trigonometry | ~10–15 marks | Identities + heights and distances. Memorise all identities, solve 30+ problems. |
| Mensuration | ~10 marks | Surface area and volume formulas. Easy marks — just memorise formulas and practise. |
| Statistics & Probability | ~10 marks | Mean, median, ogive, histogram. Probability is straightforward. |
Book: ML Aggarwal (Understanding Mathematics) or RD Sharma. Complete the textbook exercises fully — ICSE Maths papers often use similar question styles.
Science — Physics
| Chapter | Marks | Key Focus |
|---|---|---|
| Force, Work, Energy, Power | ~15–18 | Numericals on WEP theorem, machines, levers, pulleys |
| Light (Reflection & Refraction) | ~12–15 | Mirror/lens formula, ray diagrams, total internal reflection |
| Sound | ~8–10 | Characteristics, echo, sonar |
| Current Electricity | ~15–18 | Ohm's law, circuits, household wiring, electrical energy |
| Magnetism & Electromagnetism | ~8–10 | Magnetic field, Fleming's rules, motor, generator, transformer |
| Heat & Calorimetry | ~8–10 | Specific heat, latent heat, numericals |
| Nuclear Physics | ~5–8 | Radioactivity, nuclear fission/fusion, safety |
Book: Selina Concise Physics. Complete all solved examples + exercises. Practise ray diagrams daily.
Science — Chemistry
- Key chapters: Periodic Table, Chemical Bonding, Acids/Bases/Salts, Analytical Chemistry, Organic Chemistry basics, Mole Concept, Electrolysis.
- Strategy: Memorise all equations and balancing. Practise mole concept numericals daily. Learn tests for gases and salts (analytical chemistry is frequently tested).
- Book: Selina Concise Chemistry. Supplement with Viraf Dalal for additional practice.
Science — Biology
- Key chapters: Cell Biology, Genetics, Human Anatomy (Nervous System, Circulatory System, Excretory System), Plant Physiology (Photosynthesis, Transpiration), Ecology, Health & Hygiene.
- Strategy: Draw and label 5 diagrams daily. ICSE Biology marks diagrams heavily — a well-drawn diagram with proper labels can earn you 4–5 marks per question. Memorise all differences tables.
- Book: Selina Concise Biology.
ICSE board exam preparation
Super Tutor has ICSE-specific content — chapter summaries, practice quizzes, and mock exams tailored to the CISCE syllabus.
Start ICSE Prep — FreeHistory & Civics
- Civics (Section A): Indian Constitution, Parliament, Judiciary, local bodies. Factual — memorise key articles, amendments, and functions.
- History (Section B): Indian freedom movement (1857–1947), World Wars, UN, Non-Aligned Movement. Focus on dates, events, and their significance.
- Strategy: Make timeline charts for History. Create flashcards for Civics (Article numbers, fundamental rights, etc.). Solve 10 years of PYQs — ICSE History has very predictable question patterns.
Geography
- Key topics: Map work (India — rivers, mountains, cities), climate, soil types, natural vegetation, agriculture, industries, water resources, waste management.
- Strategy: Map work carries 15–20 marks — practise one India map daily. Know locations of all major rivers, mountains, passes, ports, and industrial regions. For theory, use point-form answers with relevant examples.
- Scoring tip: Geography is one of the easiest subjects to score 90+ in — maps are definite marks, and theory questions have clear answers.
Month-by-Month Plan (6 Months)

Answer Presentation Tips for ICSE
ICSE examiners value presentation. These tips can add 5–10 marks to your total:
- Use headings and subheadings in long answers (History, Geography, Biology).
- Draw diagrams wherever possible — even if not asked. A relevant diagram shows understanding.
- Label all diagrams neatly with a sharp pencil. Use arrows, not lines, for labels.
- Show all steps in Maths and Physics numericals. Do not skip steps even if the answer is obvious.
- Use point form for 5+ mark answers. Numbered points are easier for examiners to mark than paragraphs.
- Write the formula first, then substitute values, then solve. This earns step marks even if the final answer is wrong.
