Overall Exam Verdict
The 2025 CCEA AS 1 Technology and Design assessment offers a well-balanced distribution of direct recall, applied mathematical calculation, graphical communication, and extended design evaluation. While STE11 (Compulsory Design and Materials) focuses heavily on material properties, manufacturing sketches, and product analysis, STE12 provides targeted technical pathways in Electronic Control, Mechanical/Pneumatic Systems, or Product Design.
Where the Marks Are Won and Lost
- Sketching and Technical Annotation: Significant mark blocks in STE11 (Question 4 injection moulding and Question 7 wall bracket) and STE12 (Crank & Slider linkage or headrest mounting solutions) require clear, fully labelled 2D/3D working mechanisms with realistic sizes, wall fixings, and material choices.
- Calculation Precision: In the Systems options, multi-step calculations—such as compound gear train velocity ratio \(VR = \text{Driven} / \text{Driver}\), pneumatic cylinder outstroke forces, and transistor base resistor values \(R_b = (V_{in} - V_{be}) / I_b\)—yield high marks provided units and explicit substitution steps are shown.
- Quality of Written Communication (QWC): STE11 Question 6 assesses QWC through structured ergonomics and safety analysis of a consumer product. Candidates losing marks often write vague bullet points rather than distinct, technically justified explanations.
Examiner Pitfalls & Strategic Advice
Avoid giving generic descriptions of material properties (e.g., stating 'strong' instead of 'tensile strength' or 'impact resistance'). In design questions, ensure practical feasibility: show wall thickness, fixings, clearance dimensions, and specific hand tool engagement methods rather than conceptual abstractions.
