01Cells, biomolecules, heredity and metabolism
Cell biology links organelle structure with function, membrane exchange and cell division. This chapter reviews shared foundations and interprets supplied water-potential data.
2,013 words, about 10 min02Physiology, immunity, ecology and evolution
Items test how organ systems maintain internal stability, how exchange surfaces are built, and how structure at each level serves function. Negative feedback reverses a deviation: a sensor detects change, an integrating center compares it with a set point, and an effector counters it (insulin lowers glucose; sweating lowers temperature).
1,672 words, about 8 min03Physical chemistry, amounts, reactions and equilibria
This independent foundation chapter develops the mole as the currency of chemistry: balancing equations, identifying the limiting reagent, calculating yields and atom economy, and handling concentrations, dilutions and gas volumes confidently. n = m/M; n = cV with V in dm3; n = V/24.0 for a gas at room temperature and pressure, using the value given in the data provided.
2,162 words, about 11 min04Structure, bonding, materials and inorganic chemistry
This independent foundation chapter develops how the quantum-mechanical model of the atom explains the layout of the periodic table and the trends you are asked to predict: electron configuration, ionisation energy, atomic and ionic radius, electronegativity, and the evidence available from mass spectra and successive ionisation energies. Atomic number Z = protons; mass number A = protons + neutrons; isotopes differ only in neutrons, ions only in electrons.
1,795 words, about 9 min05Mechanics, fields, thermal behavior, waves and modern models
This mechanics review develops kinematics, Newton's laws, momentum, rigid-body equilibrium, circular motion, oscillations and gravitational ideas. State sign conventions, resolve vectors and justify the choice of force, energy or momentum methods.
2,118 words, about 11 min06Calculus
Calculus practice develops the ability to move fluently between a function, its rate of change, and its accumulated total. Expect differentiation of composite, implicit and parametric forms, evaluation of definite and improper integrals, and questions that require you to justify a limit before differentiating.
348 words, about 2 min07Algebra and Functions
Algebra and function practice asks you to move fluently between symbolic, graphical, and verbal representations of relationships. Expect manipulation of polynomial, rational, radical, exponential, and logarithmic expressions; solving equations and inequalities; and reasoning about domain, range, inverse functions, and transformations.
462 words, about 2 min08Physical Science: The Earth: Atmosphere, Hydrosphere, Structure Features, Geologic Processes, and History
This domain covers Earth's interior, plate tectonics, rocks and geologic time, and the atmosphere and hydrosphere. Layers: crust (oceanic basalt, thin; continental granite, thick), mantle, liquid outer core, solid inner core.
390 words, about 2 min09Practical and Experimental Skills
Instrument choice and reading, precision versus accuracy, random versus systematic error, combination of uncertainties, graph plotting and interpretation, and experimental design. Marks come from quoting a correct uncertainty with a sensible number of significant figures and from explaining why a procedure reduces error.
