The exam rewards clarity in working, correct use of units, and accurate substitution into standard formulae.
考题通常涉及基于真实工程情境的计算。例如，你可能被要求确定输送带中的拉伸应力、计算齿轮系的效率或分析液压制动系统。考试鼓励清晰的解题步骤、单位的正确使用以及准确代入标准公式。
4. Materials and Manufacturing Processes | 材料与制造工艺
This section covers the classification of engineering materials: ferrous and non-ferrous metals, polymers, ceramics, composites, and smart materials. You must know key mechanical properties such as hardness, toughness, ductility, and stiffness, and how they are tested (e.g., tensile test, impact test). Material selection is always linked to a product's functional requirements.

Re = ρvd/μ and Q = mcΔT
8. Unit 2: Design and Manufacture NEA | 单元二：设计与制造非考试评估
The NEA is a substantial project where you identify a genuine need and design an engineered solution. You produce a design folder that documents research, a product specification, generated ideas, development through modelling, final manufacturing drawings, and a production plan. Evidence of client feedback and iterative improvement is expected.
NEA 是一个大型项目，你需要识别一个真实需求并设计一个工程解决方案。你将制作一份设计文件夹，记录研究、产品规范、生成的创意、通过建模进行的开发、最终制造图纸以及生产计划。需要呈现客户反馈和迭代改进的证据。
The 'make' phase requires you to manufacture a working prototype using suitable materials and processes. You must demonstrate safe workshop practice and justify your manufacturing choices. Finally, the evaluation section involves testing against the specification, explaining failures, and suggesting further developments. This project builds evidence for the AQA marking criteria: Design, Make, Evaluate, and Technical Understanding.
“制作”阶段要求你使用合适的材料和工艺制造一个可工作的原型。你必须展示安全的车间操作，并论证你的制造选择。最后，评估部分包括根据规范进行测试、解释失败之处并提出进一步改进建议。该项目为 AQA 评分标准（设计、制作、评估和技术理解）提供证据。
9. Mathematical Skills Requirements | 数学技能要求
A minimum of 20% of the marks in Unit 1 will directly assess mathematical skills at Level 2 or above. This includes arithmetic with significant figures and standard form, algebra, geometry, graph interpretation, and basic statistics. Trigonometric functions (sine, cosine, tangent) are essential for resolving forces and analysing structures.
单元一至少20% 的分数将直接评估二级及以上的数学技能。这包括有效数字和标准形式的算术、代数、几何、图表解读和基础统计。三角函数（正弦、余弦、正切）对于分解力和分析结构至关重要。
You must be able to rearrange complex equations, substitute values accurately, and plot linear and non-linear relationships. Familiarity with gradients and areas under graphs for motion analysis (velocity–time graphs) is expected. The formula sheet provided in the exam includes many key equations, so focus on knowing when and how to apply them.
你必须能够重新排列复杂的方程、准确代入数值，并绘制线性和非线性关系图。要求熟悉运动分析中速度–时间图下的梯度和面积。考试提供的公式表包含许多关键方程，因此重点应放在知道何时以及如何应用它们。
10. Exam Tips and Common Misconceptions | 备考建议与常见误区
One common mistake is confusing stress and pressure or using incorrect units. Stress σ is force per unit area inside a material and uses N/m² or Pa, while pressure is often applied to fluids. Always write down the formula first, substitute numbers, and present the final answer with appropriate significant figures. Showing all working can earn partial marks even with a wrong final answer.
一个常见错误是混淆应力和压力，或使用错误的单位。应力 σ 是材料内部单位面积所受的力，使用 N/m² 或 Pa，而压力通常施加于流体。始终先写下公式，代入数值，并以适当的有效数字呈现最终答案。即使最终答案错误，展示所有解题步骤也能赢得部分分数。
For the NEA, students often underestimate the importance of the design folder. The folder should tell a coherent story, not just be a collection of pages. High-scoring projects show clear links between research, specification, and final outcome. Time management in the workshop is crucial; build in contingency for tooling issues. Finally, review thermodynamics and fluid dynamics early, as these topics are often covered last and can feel less familiar.
对于 NEA，学生经常低估设计文件夹的重要性。文件夹应讲述一个连贯的故事，而不仅仅是页面的集合。高分项目显示出研究、规范和最终成果之间清晰的关联。车间中的时间管理至关重要；要为工具问题留出应急时间。最后，尽早复习热力学和流体动力学，因为这些主题通常最后教授，可能感觉较不熟悉。
