GCE A/L Engineering Technology study guide
GCE A/L Engineering Technology · Work through your exam, one topic at a time.
The GCE Advanced Level Engineering Technology examination is a Sri Lankan upper-secondary qualification taken by students who intend to move into engineering, technology, or applied-science study at tertiary level or into technical employment. It is a school-leaving subject in the technology stream, assessed through a combination of multiple-choice, structured, and essay-style papers, and it rewards candidates who can connect drawing conventions, material behaviour, mechanical reasoning, electrical principles, energy concepts, production methods, and measurement practice into one coherent engineering habit of mind. The GCE A/L Engineering Technology study guide has 11 sections and about 3,523 words.
01Engineering Graphics and Design Communication
Engineering Graphics and Design Communication examines whether you can interpret and produce a correct technical drawing set: orthographic views, line conventions, dimensioning, sectioning, scales and title-block information. Marks are lost for convention errors, not for untidy lettering.
325 words, about 2 min02Engineering Materials and Their Properties
Engineering Materials and Their Properties tests the link between internal structure, processing and service performance: ferrous and non-ferrous metals, polymers, ceramics and composites, plus the standard mechanical tests used to compare them. Crystal structure controls behaviour: BCC metals such as ferritic steel are relatively strong but less ductile; FCC metals such as austenitic stainless steel and aluminium are ductile; HCP metals such as magnesium are less formable at room temperature.
305 words, about 2 min03Engineering Mechanics and Applied Mechanics
Engineering Mechanics and Applied Mechanics tests equilibrium and motion: free-body diagrams, reactions, trusses, friction, centroids, and the dynamics topics of kinematics, energy, momentum and circular motion. A body in equilibrium satisfies ΣF = 0 and ΣM = 0.
340 words, about 2 min04Electrical and Electronic Technology
Electrical and Electronic Technology tests DC and AC circuit analysis, machine and transformer principles, basic electronics, and safe wiring practice. Expect calculations, not just descriptions.
344 words, about 2 min05Thermodynamics and Energy Technology
Thermodynamics and Energy Technology tests energy conversion in closed and open systems: the first law, gas processes, engine and refrigeration cycles, steam, and the three heat-transfer modes. First law for a closed system: Q − W = ΔU.
313 words, about 2 min06Manufacturing, Workshop and Production Technology
Manufacturing, Workshop and Production Technology tests how parts are made and how processes are selected: casting, forming, joining, machining, CNC and production organisation, with workshop safety implicit throughout. Casting: a pattern is larger than the part by a shrinkage allowance and tapered by a draft allowance; a riser feeds solidification shrinkage; sand cores form internal cavities.
339 words, about 2 min07Measurement, Instrumentation and Control
Measurement, Instrumentation and Control tests whether you can choose an instrument, read it correctly, quantify error, and describe a control loop. Accuracy is closeness to the true value; precision is repeatability.
317 words, about 2 min08Civil and Construction Technology
Civil and Construction Technology tests the materials, structural elements, construction methods and site controls used in buildings and simple infrastructure. Concrete is cement, fine aggregate, coarse aggregate and water, with the water/cement ratio controlling strength and durability: lower w/c gives higher strength but lower workability.
330 words, about 2 min09Engineering Drawing and Computer-Aided Drafting Practice
Engineering Drawing and Computer-Aided Drafting Practice tests the transfer of drawing convention into CAD: coordinates, layers, dimensions, blocks, 3D modelling and plotting. Set units and drawing limits first; model full size, then plot at a scale.
301 words, about 2 min10Engineering Project
Engineering Project tests the process of solving a real problem: identifying a need, specifying requirements, planning, building, testing, evaluating and reporting. Aims are broad intentions; objectives are specific, measurable and time-bound.
287 words, about 1 min11Safety and Professional Practice
Safety and Professional Practice tests risk control, legal duties, workshop and electrical safety, fire response, environmental responsibility and ethical conduct. Risk assessment: identify hazards, decide who may be harmed and how, evaluate risk (likelihood × severity), record controls, review.
