CCEA GCSE Technology and Design splits into a shared core paper plus one specialist option. This page maps where the marks sit in Unit 1 and shows the flowchart, mechanism and safety-writing habits examiners keep marking down.

ข้อกำหนดเครื่องคิดเลข
A calculator is useful for the gear, pneumatic and electronic calculations in this subject, and CCEA's general rule applies: no calculator with a computer algebra system, no borrowing a calculator from another candidate, and nothing stored in memory that could be retrieved during the exam, including formulae, notes or text. If your calculator has an exam mode, switch it on. It clears stored data far more reliably than the reset button, which only resets display settings and leaves stored programs or text in memory.
AO1: AO1: recall, select and communicate their knowledge and understanding of technology and design in a range of contexts (30%)
AO2: AO2: apply skills, knowledge and understanding, including quality standards in a variety of design contexts, and plan and carry out investigations and making tasks involving an appropriate range of tools, equipment, materials and processes (40%)
AO3: AO3: analyse and evaluate evidence, design proposals and outcomes, make reasoned judgements and present conclusions and recommendations (30%)
วัตถุประสงค์: Carries an exact driver-to-driven tooth ratio into a velocity or output speed calculation without a rounding slip partway through a compound gear train question.
ใช้เมื่อใด: Any compound gear train, pulley or velocity ratio question with more than one calculation stage.
ขั้นตอน
Work out the driver-to-driven tooth ratio, then press ANS to feed that exact value straight into the velocity or output speed calculation, instead of writing the ratio down and retyping a rounded version.
ข้อควรระวังในการสอบ: This is a live, in-exam technique only. CCEA and JCQ ban anything stored in a calculator's memory before the exam, including formulae or old working, so clear your calculator and switch on exam mode if it has one before you sit down.
Work pneumatic force out in one continued calculation
Casio fx-83/85 series (scientific)
วัตถุประสงค์: Removes the risk of forgetting to subtract the piston rod area, or rounding it too early, in an instroke force calculation.
ใช้เมื่อใด: Any pneumatic cylinder force or air consumption question involving the piston rod area on the instroke.
ขั้นตอน
Calculate the full piston area, subtract the rod area, and multiply by pressure in one continuous calculator entry using brackets, so no intermediate area needs to be written down and retyped.
ข้อควรระวังในการสอบ: Use this only for figures calculated during the exam. No stored programme or formula list is permitted in the calculator you bring in.
Use memory recall for Ohm's law and power chains
Casio fx-83/85 series (scientific)
วัตถุประสงค์: Keeps a current value exact when it feeds into a following power calculation, instead of reintroducing rounding error.
ใช้เมื่อใด: Any electronics question that gives voltage and resistance and then asks for power, or chains two circuit calculations together.
ขั้นตอน
Calculate current from voltage equals current times resistance, store it with the memory-store key (M+ or STO), then recall it (MR or RCL) for the power calculation rather than retyping a rounded figure.
ข้อควรระวังในการสอบ: This works only with values found live in the exam. Clear your calculator's memory beforehand: a manual reset does not remove stored data, so use exam mode if your calculator has one.
ข้อผิดพลาดที่พบบ่อย
1highคะแนนที่เกี่ยวข้อง: 2Computer Control Systems and Flowcharts
Leaving a decision box in a flowchart evaluating to 'No' without a return loop arrow, so the routine never closes.
วิธีหลีกเลี่ยง: Trace every path from the start of the flowchart to an end point before submitting it. Any decision box needs a labelled path out for every outcome it can produce.
2mediumคะแนนที่เกี่ยวข้อง: 1Mechanical Control Systems: Motion, Components and Mechanisms
Giving a gear, pulley or velocity ratio as a bare number or fraction instead of the standard ratio format, for example '4' instead of '1:4'.
วิธีหลีกเลี่ยง: Always write the answer with a colon, even if the working already makes the value obvious. The mark scheme rewards the format, not just the number.
3mediumคะแนนที่เกี่ยวข้อง: 2Potential Dividers, LEDs, Thyristors and Transistors
Drawing a flywheel diode across an inductive relay coil with the wrong polarity or not in parallel with the coil.
วิธีหลีกเลี่ยง: Learn the standard protection circuit by heart: the diode goes in parallel with the coil, cathode toward the supply, so it conducts only when the coil's field collapses.
4highคะแนนที่เกี่ยวข้อง: 1Tools, Processes and Production Methods
Naming a generic tool such as 'marker' or 'saw' in manufacturing questions instead of the precise piece of equipment the mark scheme wants, such as odd-leg calipers, a scriber or a bradawl.
วิธีหลีกเลี่ยง: Learn the correct name for every marking-out and measuring tool in the specification, not just what it looks like or does.
5highคะแนนที่เกี่ยวข้อง: 3Pneumatic Systems and Control
Calculating pneumatic instroke retraction force from the full piston area, forgetting to subtract the piston rod's cross-sectional area first.
วิธีหลีกเลี่ยง: Work out the full piston area and the rod area as two separate steps, subtract them, and only then multiply by pressure. Show all three numbers in your working.
6mediumคะแนนที่เกี่ยวข้อง: 2Potential Dividers, LEDs, Thyristors and Transistors
Confusing the base, collector and emitter terminals of an NPN transistor when labelling or completing a schematic diagram.
วิธีหลีกเลี่ยง: Practise labelling a bare transistor symbol from memory until the three terminals are automatic, rather than relying on recognising a complete circuit.
7highคะแนนที่เกี่ยวข้อง: 3Health and Safety; CAD and CAM
Writing vague safety platitudes such as 'wear protection' in extended QWC answers instead of naming the actual equipment involved, such as machine guards, chuck keys or sacrificial boards.
วิธีหลีกเลี่ยง: Before you write a safety point, ask what specific piece of equipment or procedure it refers to, and name it. A general statement earns nothing on its own.
