Draw atomic models for the first 20 elements showing protons, neutrons, and electron distribution in shells.

Distinguish ionic, covalent, and metallic bonding by predicting bond type for 12 element pairs using electronegativity and electron transfer/sharing.

Compare plant and animal cell organelles and state one function for each of the eight major organelles.

Sequence the stages of mitosis and meiosis and identify one key event that distinguishes them.

Explain the role of enzymes, diffusion, osmosis, and active transport in nutrient absorption and gas exchange.

Solve monohybrid and dihybrid genetics problems for dominant, recessive, and sex-linked traits using Punnett squares.

Outline the evidence for evolution (fossils, homologous structures, molecular similarities) and distinguish natural selection from Lamarckian inheritance.

Balance 15 chemical equations and classify each as combination, decomposition, displacement, or double displacement.

Predict products of reactions between acids and metals, bases, and carbonates, and write balanced equations for each.

Rank common metals by reactivity and predict single-displacement outcomes using the activity series.

Compare properties of ionic and covalent compounds and relate them to melting point, conductivity, and solubility.

Name and draw structural formulas for the first six alkanes, alkenes, and alcohols and identify functional groups.

Explain the role of each major organ system (digestive, respiratory, circulatory, excretory) in maintaining homeostasis.

Identify deficiency diseases (scurvy, rickets, beriberi, anaemia) and match each to its missing nutrient.

Distinguish communicable from non-communicable diseases and describe prevention and transmission routes for five common diseases.

Interpret a food label against daily nutrient requirements and calculate the energy content of a sample meal.

Describe first-line immune defences and how vaccination produces immunity.

Calculate speed, velocity, acceleration, force, work, power, and efficiency from given data sets with correct units.

Draw and interpret distance-time and velocity-time graphs, extracting acceleration and distance travelled.

Apply the lever, pulley, and inclined-plane formulas to compute mechanical advantage and efficiency for three simple machines.

State and apply the work-energy theorem to a falling object and a braking vehicle.

Design a controlled experiment, identifying independent, dependent, and controlled variables, and report measurements with appropriate precision and significant figures.

Ray-diagram image formation for concave and convex mirrors and lenses, and calculate image position and magnification with the mirror/lens formula.

Explain reflection, refraction, dispersion, and total internal reflection with one everyday application each.

Relate wave speed, frequency, and wavelength and calculate one from the other two for sound and light.

State Ohm's law and compute current, voltage, resistance, and power in series and parallel circuits.

Distinguish conductors, insulators, and semiconductors and describe one safety application of fuses and earthing.

Trace energy flow and nutrient cycling (carbon, nitrogen, water) through a food web and identify producers, consumers, and decomposers.

Distinguish renewable from non-renewable resources and evaluate one management strategy for each.

Explain biodiversity loss, pollution, and climate change as interacting environmental pressures with one local example each.

Describe evidence for common ancestry and classify organisms using a simple dichotomous key.

Propose a conservation action plan that names a resource, a threat, and a measurable intervention.

Complete three timed mixed-domain practice sets and score at least 75% on each.

Review every missed item, tagging it to its domain and writing a one-line correction rule.

Re-derive the five highest-yield formulas (Ohm's law, lens formula, work-energy, mechanical advantage, Punnett ratios) from memory.

Summarise each domain in a single index card of key definitions and one worked example.

Simulate exam conditions with one full-length timed paper and record per-domain accuracy.
