| Logarithms, Indices | Every calculation-heavy Class 10 chapter | Slow, error-prone working under a two-hour paper |
| Expansions, Factorisation | Quadratic Equations; Remainder & Factor Theorems | Class 10 assumes the manipulation and teaches only the theorem |
| Triangles, congruency | Similarity | Similarity is the largest Class 10 geometry block |
| Mid-point Theorem, Rectilinear Figures | Circles; Tangents and Chords | Angle-chasing in proofs stops working |
| Trigonometrical Ratios, Standard Angles | Trigonometrical Identities; Heights and Distances | The ratios are never taught again |
| Co-ordinate Geometry, Distance Formula | Section Formula; Equation of a Line; Reflection | Class 10 starts where Class 9 stopped |
| The Language of Chemistry, valency | Mole Concept and Stoichiometry | The heaviest numerical chapter in ICSE Class 10 Chemistry |
| Atomic Structure and Bonding | Periodic Properties; Chemical Bonding; Electrolysis | Electrolysis becomes memorisation instead of reasoning |
| Motion, Laws of Motion, Fluids | Force, Moments, Machines, Work and Energy | Class 10 physics is mostly applied Class 9 physics |
