01Engineering models, drawings, evidence and project decisions
Engineering reasoning starts with a purpose, a system boundary and the assumptions that permit a calculation. A free-body diagram, circuit diagram, energy-flow model and process chart represent different relationships.
455 words, about 2 min02Materials, testing and selection
This independent materials study checks whether you can go from a material's internal structure to a measurable property and from there to a choice justified with numbers. The usual content is metals, polymers, ceramics and composites, the tensile test with its stress–strain curve, hardness and impact tests, and selection using specific indices.
489 words, about 2 min03Building systems, load paths, heat and moisture
Building Materials and Their Properties tests whether you can select a material for a job and justify it with properties and simple numbers. The exam expects strength, durability, thermal behaviour, workability and specification.
1,025 words, about 5 min04Energy, thermal machines and environmental assessment
This domain asks you to compare energy sources, apply conversion efficiencies with correct units and assess sustainability. Typical items are a hydraulic or wind power calculation, a thermal efficiency question and a comment on the environmental impact of the energy mix.
429 words, about 2 min05Electrical circuits, machines and digital logic
This domain covers DC and AC circuit analysis, transformers and rotating machines, power converters and Boolean logic. This foundations field usually mixes a quantitative circuit problem with a simplification of a logic function.
430 words, about 2 min06Measurement, feedback, PLC and automation
This domain tests whether you can describe a control loop, choose a sensor from its specifications, explain what a PLC does in each scan and justify a robot morphology. Expect questions on sensor characteristics, PID behaviour, PLC I/O and degrees of freedom.
489 words, about 2 min07Computing Systems
This shared-core guide covers hardware, operating systems, storage, virtualization, system security, and networking. Practice explaining instruction execution, memory, resource management, and controls against specified risks.
727 words, about 4 min08Calculus
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 min09Algebra 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 min10Physical 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.
