Syllabus by topic
How science builds on itself over time; the physical and hormonal changes during adolescence; nutrition, respiration, and circulation in animals; photosynthesis, transport, and reproduction in plants.
Properties of acids, bases, and neutral substances using indicators; physical and chemical properties of metals and non-metals; distinguishing between physical changes (reversible) and chemical changes (new substance formed).
Circuit components and how circuits work; conduction, convection, and radiation; measuring speed using distance–time graphs; how light travels, forms shadows, and reflects.
Movements of the Earth and Moon, phases of the Moon, eclipses, and the Sun–Earth–Moon system — often tested through diagram-based questions.
Practice bridge
Step 1
Generate 10 Biology questions on life processes in animals and plants, and adolescence changes.
Step 2
Create Chemistry MCQs on acids and bases, metals vs non-metals, and physical vs chemical changes.
Step 3
Ask for a Physics + Space drill on electric circuits, heat transfer, distance–time graphs, and the Earth–Moon–Sun system.
