Osaka Public High School Entrance Examination - Science study plan

Draw free-body diagrams for at least six situations (falling object, object on a slope, two forces at an angle) and label every force with its correct direction and source.

Calculate average speed, instantaneous speed, and acceleration from distance–time and velocity–time graphs across ten given examples.

Solve twelve net-force and Newton's-law problems, writing the equation symbolically before substituting numbers.

Decide whether work is done in eight everyday situations, then compute work and power for the cases where it is.

Distinguish transverse from longitudinal waves and compute frequency, wavelength, and wave speed in ten given cases.

Draw ray diagrams for a plane mirror, a convex lens, and total internal reflection, stating image type, orientation, and size for each.

Apply Ohm's law and series/parallel resistance rules to ten circuits, calculating current, voltage, and power at every resistor.

Explain electromagnetic induction and the principle of the electric motor in four sentences each, supported by a field-line sketch.

Classify twenty substances as element, compound, or mixture, and justify each classification in one clause.

Sketch particle models for solid, liquid, gas, and for a solute dissolving, then contrast chemical change with physical change using those models.

Compute mass-percent concentration and solubility for ten solution problems, including one saturation case.

Choose and justify a separation method - filtration, distillation, chromatography, or recrystallization - for six given mixtures.

Write and balance fifteen chemical equations covering combination, decomposition, and displacement reactions.

Predict precipitates using a solubility table and write ionic equations for six reactions that form them.

Calculate reactant and product masses from balanced equations in eight problems, including two limiting-reactant cases.

Describe oxidation and reduction in terms of both oxygen transfer and electron transfer, giving four examples of each.

Label the organs of digestion, gas exchange, and circulation on a blank diagram and state the function of each in one sentence.

Compare photosynthesis and respiration by listing raw materials, products, energy flow, and the organelles involved.

Trace the path of blood through the heart, lungs, and body, noting where oxygen-rich and oxygen-poor blood travel.

Interpret experimental data on enzyme activity, transpiration, or breathing rate and state the conclusion supported by the data.

Solve monohybrid crosses for eight genetics problems, stating genotype, phenotype, and expected ratios.

Explain mitosis and meiosis in terms of chromosome number and the purpose of each, using simple sketches.

Describe how fossils and geological strata indicate past environments and the relative age of rock layers.

Read a stratigraphic column and place its layers in correct time order, citing two pieces of evidence.

Interpret weather maps by identifying fronts, pressure systems, and the resulting wind and rainfall patterns in five cases.

Explain land and sea breezes and the formation of clouds and rain using temperature, humidity, and pressure terms.

Describe the apparent motion of the Sun and stars, and explain seasons and moon phases from Earth's tilt, rotation, and revolution.

Compare the internal structure and surface conditions of the terrestrial and gas-giant planets in a short written summary.

Take two full-length timed mock papers under exam conditions and record the score for each domain separately.

Rank your missed questions by error type - misread, formula forgotten, concept gap, or calculation slip - and quantify each type.

Re-teach the two weakest topics per domain by rewriting the explanation and redoing five related problems.

Assemble a final one-page cue sheet of laws, formulas, and key diagrams you must recall instantly.
