1. Understanding the SQA Engineering Pathway | 了解 SQA 工程课程路径
In Scotland, Year 11 (S4) students typically sit National 5 qualifications. Engineering Science at this level introduces systems thinking, basic mechanics, electronics, and programmable control. The following year, many learners progress to Higher, which deepens both theoretical understanding and practical design work.
在苏格兰，Year 11（S4）学生通常学习 National 5 课程。这一级别的工程科学介绍系统思维、基础力学、电子学和可编程控制。第二年，许多学生会升入 Higher 课程，该课程会深化理论理解和实践设计工作。
Higher Engineering Science is designed to build directly on National 5 knowledge. However, the pace is faster, the analytical demands are greater, and the coursework requires more independent problem-solving. Recognising this structure early allows you to plan an effective transition.
Higher 工程科学旨在直接建立在 National 5 知识之上。然而，其节奏更快、分析要求更高、课程作业也需要更独立的解决问题的能力。尽早认清这一结构，有助于你计划有效的衔接。
2. National 5 Engineering Science: A Quick Recap | National 5 工程科学快速回顾
Before mapping out your next step, it is worth reviewing the core topics covered at National 5. The course is divided into three main units: Engineering Contexts and Challenges, Electronics and Control, and Mechanisms and Structures.
在规划下一步之前，值得回顾 National 5 涵盖的核心内容。该课程分为三个主要单元：工程背景与挑战、电子与控制，以及机械与结构。
