JCE General Science (Syllabus 43) study plan

Distinguish independent, dependent and controlled variables in six short written scenarios, naming each one explicitly.

Convert between SI units (length, mass, volume, time, temperature) and compute derived quantities such as density and speed, reporting answers to the correct number of significant figures.

Construct and interpret line and bar graphs from raw data, including choosing scales, labelling axes with units, and calculating a slope.

Differentiate accuracy from precision and identify at least three likely sources of error in a simple measurement, stating how each is reduced.

Draw and label a plant and an animal cell, and describe the function of each named organelle in one sentence.

Compare plant, animal and bacterial cells across at least four features in a table.

Explain diffusion, osmosis and active transport and predict the direction of water movement in given concentration scenarios.

Design a controlled investigation into osmosis in plant tissue, specifying variables, sample size, controls and how the result will be measured.

Trace the path of food, blood and air through the digestive, circulatory and respiratory systems, and state the function of each major organ involved.

Explain how enzyme activity changes with temperature and pH, and interpret a supplied enzyme-rate graph.

Interpret tables and graphs of pulse rate or breathing rate to draw two evidence-based conclusions.

Distinguish sexual from asexual reproduction and outline the main stages of the human reproductive cycle at a general level.

Deduce proton, neutron and electron numbers from atomic notation and relate them to group and period position.

Classify elements as metals, non-metals or metalloids and predict the ion each is likely to form.

Distinguish ionic from covalent bonding using electron transfer and sharing descriptions with one example each.

Select an appropriate separation technique (filtration, distillation, evaporation, chromatography, magnetism) for five given mixtures and justify each choice.

Write word equations for common reactions and convert them into balanced symbol equations.

Apply the law of conservation of mass to predict missing masses in reaction data.

Classify substances as acids, bases or neutral using pH values and describe neutralisation in words and symbols.

Interpret rate-of-reaction data to identify the effect of temperature, concentration or surface area, controlling variables in the analysis.

Calculate speed, acceleration, force, work, power and efficiency using the correct formula and units, showing full working.

Interpret distance-time and velocity-time graphs, extracting speed, acceleration and total distance travelled.

Draw and interpret simple series and parallel circuits, applying V = IR to find an unknown quantity.

Describe energy transfers and transformations in at least four everyday devices and state where energy is lost.

Classify rock samples or descriptions as igneous, sedimentary or metamorphic and place them on a rock-cycle diagram.

Explain the events at constructive, destructive and conservative plate boundaries and link them to earthquakes and volcanoes.

Read a weather or climate data table to describe seasonal patterns and distinguish weather from climate.

Evaluate renewable and non-renewable energy resources using supplied cost and output data, and recommend one for a stated community.

Propose an evidence-based solution to one local environmental issue, naming the technology or practice involved.

Complete a full-length timed mock paper under exam conditions without notes.

Classify every error by domain and by error type (knowledge gap, misread question, calculation slip, unit error).

Re-teach the two weakest topics using the error log and produce a corrected worked example for each.

Compile a one-page formula, unit and key-definition sheet from memory, then verify and correct it against notes.
