Distinguish between acids, bases and salts using indicator logic and pH reasoning, and predict neutralisation products for 10 reactions.

Explain oxidation and reduction in terms of electron and oxygen/hydrogen transfer, and identify the oxidising and reducing agent in 8 given reactions.

Describe the properties and uses of at least 6 common metals and non-metals and justify one alloy choice for a stated application.

Compare the reactivity of metals with water, acids and salt solutions, and rank a given set of 6 metals into an activity series with justification.

Explain the extraction of a moderately reactive metal from its ore in sequence: concentration, roasting/calcination, reduction and refining.

Differentiate plant and animal tissues by structure and function, and draw labelled sketches of parenchyma, xylem and phloem.

Describe the structure and function of the nephron and of the human digestive tract in the correct sequence.

Explain the processes of nutrition, respiration, transportation and excretion in plants, linking each to a named structure.

Trace the human respiratory and circulatory pathways and state where exchange of gases and materials occurs.

Distinguish reflex action from voluntary action and label the parts of a reflex arc.

Compare asexual and sexual reproduction in flowering plants and state the function of each floral part.

Explain heredity using Mendelian monohybrid crosses and predict offspring ratios for given parental genotypes.

Distinguish acquired from inherited traits and describe sex determination in humans.

Evaluate a balanced diet for an adolescent and identify deficiency diseases linked to iron, iodine, vitamin A and vitamin C.

Outline personal hygiene and safe food-handling practices and explain the mode of spread of two common communicable diseases.

State and apply the laws of reflection and refraction to draw ray diagrams for concave and convex mirrors.

Use the mirror and lens formulae to calculate image distance, magnification and nature of image for 10 numericals.

Explain dispersion and scattering of light and account for the blue colour of the sky and the reddening of the sun at sunrise.

Describe the human eye's defects (myopia, hypermetropia, presbyopia) and state the corrective lens for each.

Apply Ohm's law and the series/parallel resistance formulae to solve 10 circuit numericals.

Compute electrical energy consumed and cost of electricity for household appliances using power and time.

Explain the heating effect and magnetic effect of current and state one application of each.

Draw and interpret the pattern of magnetic field lines around a straight conductor and a solenoid.

Classify natural resources as renewable and non-renewable and explain two consequences of their over-exploitation.

Describe the causes and effects of air, water and soil pollution and suggest one control measure for each.

Explain the greenhouse effect, ozone depletion and the water cycle with correct cause-effect links.

Write the aim, apparatus, procedure, observation and conclusion for 5 standard school experiments in physics, chemistry and biology.

Interpret data from a table or graph and draw a valid conclusion, practising 5 data-interpretation items.

Apply science concepts to everyday situations such as why a metal vessel is not used in a microwave or why salt is added while boiling water.

Revise the full syllabus through a timed mock covering all 8 domains and analyse errors by domain.

List and correct the 10 most frequent mistakes found in the mock, then re-attempt those items.
